How to Balance Redox Equations in Basic Solution
Вставка
- Опубліковано 27 чер 2015
- We'll go step by step through how to balance an oxidation reduction (redox) reaction in basic solution. The process is similar to balance an oxidation reduction equation in acidic solution. Most importantly, both charges and atoms must balance. Here are the steps: first, calculate oxidations numbers for all the elements in the equation. Next, figure out what is being oxidized and what is being reduced. Then, write half reactions for the oxidation and reduction. After that, balance each half reaction: first, for the atoms other than O and H, then for O and H, and finally for charge by adding electrons. After being balanced, the oxidation and reduction half reactions are ready to be added back to together. Make sure that the number of electrons is the same in the oxidation and reduction half reactions. If they are not, multiply one or both of the half reactions to make the number of electrons the same. Then, combine the oxidation and reduction half reaction, canceling out stuff that appears on both sides of the equation. To get rid of the H+ ions, add OH- (hydroxide) ions to both side. Then combine the H+ and OH- to make water, H2O. Finally, subtract out any H2O molecules you can from both sides of the equations. Lastly, do a final check to make sure that everything balances: both atoms and charge.
My goal in life is to be as happy as this man when doing chemistry
looooool
thumbs up bro
Amen!
Mission Impossible!

Why can't every teacher be as good as Tyler, enthusiastic and clear.
That's what I'm saying!!! He should clone himself
You're an absolute legend man
HELLO SUBSCRIBER FROM INDIA..
@@cashcartibtch9238 same bro
It's cute how he suddenly talk about outside of his life for a second lmao
Ikr😂
Ah, no...
Mr. Tyler DeWitt, you are a savior in the chemistry students world. Thank you.
awe
if your students need him as their savior that just means youre a terrible teacher
ingram450g I don't think your reading is too great. She is herself a student, and in my opinion, this video was so helpful, so stop being a pretentious commenter, give this video a like and if not.... Just leave the comments?

I live in Sweden and I study pharmacy at university. I usally sit more than six hours everyday to watch and try to understand lectures about chemistry that my teachers upload. The length of one avarge lecture is about 1,5-2 hrs, and includes a whole chapter from a book that the teacher tries to explain in detail. Unfortunately, I get lost and in the end I start to question my choice of subject. However, I found you here on youtube, and let me tell you that you cover everything that my teachers tries to explain within or even less than one hour. Not only do you go over everything in detail within a short amount of time, you do it in a way I never seen someone teach before, passionated and with an pedagogical effect. You really make everything easy, your stratergy of breaking the topic down into smaller pieces and putting them togehter is phenomenal. I've learned more from you than I do from my teachers, who are professors and doctors!
I want to thank you for your dedicaton and for taking your time to upload videos! If i pass my exams, it will be thanks to you, If I don't, it is still thanks to you that I understand things I thought I'd never understand, which is a huge goal for me.
THANK YOU :D
Leila i do this at 15 🥺
Well said
So true
Yess soo truee!!
So did u become a pharmacist?
Is it only me or I’m actually enjoying balancing these redox reaction? Plus the way you teach everything step by step makes it more simple and fun!!!!
I know right
It so easy when he balances redox reactions
yes. yes, it's only you : |
For real ! Chemistry is so fun
please my friend , please don't stop making those UA-cam explanations for Chemistry . Chemistry has become easy with your UA-cam videos . You take a long time and you suffer to make those videos , but trust me you'll be the best teacher for chemistry if you go on like this . Thanks again my brother .
i don't think he suffers when making these videos, can't you see how excited he looks in the face cam?
@@de_soot He meant that he puts a lot of effort and time in making these videos :)
@@de_soot dude😭😭😭😭😭😭
4:50,
You have made chemistry More interesting to me, you teach well.😊
Dammmmmmn it’s been four years since I have commented on that
Going to watch all the advertisements on all your videos to help you since I'm a broke college student... It's the least thing I can do as a THANK YOU!
That's both respectful and cute
bruh... u have to click on them for him to earn money... just watching it won't do it. Don't want u to waste ur time XD. good intentions tho :)
Wait how do u donate
@@josephlin5363 nope, youtubers make money off of showing ads. whether people click or not is the advertiser's problem
@@inkbery4473 really?
if this guy wasnt around i would probably fail chemistry.
Qano same lol
Angelo Kwek lmao I'm failing it right now 😂 fail hard or go home
Angelo Kwek loser...
Angelo Kwek same
@Qano 😂
He literally saves me from failing my exam. He deserves a million subscribe and his video should be used in school for teaching students.
Does basic solution means the easy way to balance redox reactions?
My college chem teacher actually does use his videos, and every time I see one, I always understand concepts way better then when reading the textbook. Maybe I learn better visually then through reading.
The last "couple steps" are for basic solution from 12:33. Preceding steps are same for acidic solution.
thank you
Thanks! I can't understand the adding H2O molecules and balancing OH- ions in basic medium. I am almost perfect with acidic medium
Just wish I had a teacher like you in school that would help me a lot. Dude you are just awesome. Nobody can beat you in teaching chemistry. Thumbs up
Yo even i hope i could have someone like this as my chem teacher
he is a good teacher always accurate
@@divinefavourdivinefavour4961 why did he stop making videos ?? 😔
does anyone else get excited about chem just because he is so excited..?
+Sarah Cito no i can't be as excited
yeah, just watching him make you feel it's awesome ^0^ !!
despite this great man i'll never get to love chemistry..
Yeah 😂
same here
ya ify
OMG THIS GUY SAVED MY CHEMISTRYYYY
same here
im so excited
Helping my daughter with her chem and refreshing my aging memory. Your explanations are absolutely perfect! Thank you professor
4:46 - 5:00 is the best part of the video...you are the cutest
Angela Pedrigal Completely I agree. You can see his love and passion for Chemistry 🥰.
lmao ikr
Lol
English isn't My native language and i don't study in english medium but you make it so easy for me to learn through your own style. thank you very much for helping.. you are a great teacher..!
hehe
Yes me to
Me toooo!!! Help loads at my Uni..
This man is the best I've ever seen in explaining in chemistry
Almost every time when I need consultation for chemistry during my work, before going to the lecturer again, I make it a point that I search for your relevant videos man, simply because you make things as simple. you are just the best with chemistry, all that difficultness of chemistry goes away with you. thumbs up for real.
The effort you put into your videos really reflects on our understanding of the concept
Cheers man
agree
General Kenobi?
i love you... you just saved me from the impossible task of reading through a chapter in a textbook while sleep deprived...
I'll be taking an exam on chemistry tomorrow and this 18 minute video have taught me more than my teacher who spent over 5 days to teach this to us. My greatest salute on you, sir! Thank you so much 😄
How was the chemistry test?
@@pranaydave5536 i guess it was bad because he deactivated his youtube channel
My teacher taught this lesson for just 30 mins and then gave us a quiz 😩
I can't imagine my life without this channel literally!
Can you replace my chemistry professor uhhh you rock!!!
You're amazing! I was really struggling with oxidation-reduction reactions, and I just couldn't understand anything my professor was explaining. You broke it down in a way that I had never seen before, you explain it so detailed that it makes it so much easier to understand! Thank you so much for helping so many of us!!!
I love this guy sm he makes you feel so calm and hes so friendly and makes it easy for everyone to understand
I just love his teaching. He explains everything so clearly! I watch him for whenever I need help. Thx Tyler
I disable adblock for you.
great comment :D
?
lmao
lmao
Best comment I've ever read xD
hey tyler u dont realise it bro but ur such a great help. thanks so much man !!!!!!!!!!!!!
You just saved my life with this video! I could not understand it AT ALLLLL until I watched this. I love how you break down something complex and make it simple and clear. Your notes are absolute goals and provide an excellent format for my own chem notes! This is my go to channel when I am lost in chem... which is basically everyday. You are a chem God. Thank you soooo much.
His organizational skills are GOALS!!! Thank you Tyler!!
he teaches soooooo well that my 6 yr brother understood everything!
Damien Blue haha this is BS
Lol
Okay this is BS
Girl......
*clears throat*
One does not need to have been learning chemistry previously before understanding from you.
You are an amazing teacher! You teach in an easy-to-understand fashion.
I don't think you understand how much this helped! You are great!
Thank you so much for caring when others don't. It helps more than you could ever know.
i was reading in romanian the chemic lessons, and i didnt understand anything, so i found you on youtube and in english (another language for me)i understood better than in my native language. ....youre the best, youre doing good things! please do more!
SAME
This guy is a legend! Thank you Mr. DeWitt! :)
I just want to say THANK YOU. I was on the verge of tears doing ALEKS homework on this. I finally found your videos and you explained it PERFECTLY!
I watched all of your videos on redox equations. You explain everything very well and you really helped me understand the material. I appreciate all the work you put in for these videos, I subscribed to you and hope to see more soon. Thank you!
Thank you Mister !
You helped me so much with your videos and made everything so simple.
Awesome work, you get a new sub.
Tyler you are awesome ! I'm in love with all of yours' video lectures.. you are the best Chemistry teacher I've ever known !
The simplest, most effective n the most satisfying method to understand chemistry I saw with u.
Thank you so much
literal life saverrrrrr!! also, you look so happy doing these videos, it makes me happy too
basic part starts at about 12:30 :) thank you for this video, really appreciate all you do to help others understand chem!
Thank you for this! This was a chemistry masterclass
You are awesome. Thank you! I manage to understand everything in this 18 min video. (I'm not able to understand anything in the school notes/lessons and the 30 powerpoint slides that are provided.) Thank you so much!!! I like the way you smile with enthusiasm when explaining all these in great details, and ending it with a very good summary.
And I was crying over this for almost a week! If any teacher is reading this comment, I highly exhort you to never assume that the student you are teaching knows the "SIMPLE STUFF" already, even if he's an intelligent person. They sure do know thecontextual feel of the topic but it's always good to teach things in the same way you would teach a nursery kid. How much time will it consume? Probably 4-5 minutes per 40 minutes lecture to talk about every thing that may be potentially ambiguous
Thank you so much for making this video; I've been absent from class for a week (I was in the hospital) and my teacher is still making me take the test tomorrow. I didn't understand anything, but thanks to this, I may actually pass. Thank you!!
All the doubts, confusion are gone..thank you so much sir, all concepts are cleared ♥️ God bless you 🪄
And I finally understand. Thanks a lot, you are the BEST!
OMG I was so happy when I found there's your video on balancing redox. you save me everytime. thanks
Wow, I literally have an exam in an hour and I was still really confused about balancing redox equations so I decided to look it up on youtube because, well why not? I came across this video and I absolutely can not thank you enough!!! This made it so so simple! Thank you! Thank you! Thank you!
Hope you Aced the exam tho
Thank you Man U r great no doubt .
I'm weak in chemistry and your videos help me to be best one in iraq😉.
ALLAH Protect you ❤️❤️
Keep uploading more video .
Luv u 😎

Wtf are you, 8 years old? Get a life
@@davisjohn1517 Stop insulting people's identity. You're the worst kind of person on the internet
Dude there was nothing BASIC about this, this was intense. Thank you so much for having the patience to walk us through it.
You are really my helper. I will keep the bell ding and watch all your videos as a support. Thanks very much
you are fantstic man.
i was about to fail chemestry in college but got thru with pretty good grades bcz of you! thanks!!
Thank you so much for making these videos you are legit saving my exams, I hope you make more videos focusing on edexcel IAL chemistry i would be happy to donate!
this is the most helpful chem video i’ve ever watched
I always come back to this video!! You're an amazing teacher! :D
I wish I was this happy has you when doing chemistry XD
+rejinmae His smile makes a whole difference.
ikr?
this man saved my life......3 teachers taught me redox reaction, but the only man who helped me balance redox reactions correctly is Tyler DeWitt....thank u sooo much!!!!!!!!!!
Out of all the Chemistry tutorial group iv watched so far, Tyler, yours is the most understandable and easy to learn.
Please keep up the good spirit.
May GOD bless your hard working.
♥️🤝🏽
this channel is a godsend! i don't think I could get a an A AP Chem without it, thank you so much!
I love these videos!!!!!
big W
Your happiness doing chem make me smile...
me too:,)
you are a life savior,thank you very much for the videos!! god bless you.
This has helped me a lot! I love your clarity
OMG Thank you so much!
Seriously, I'm loving chemistry because of you!
I got chemistry 03/30 in my first cat in the university but now I have become an assistant lecturer... chemistry is so sweet
You are great! I learned more from this video than two classes.
Mind-blowing explanation! This topic has never been so clear! It's evident how much you enjoy teaching chemistry, you made it so much fun. Thank you, Mr Tyler! :)
thank you thank you thank you thank you thank you :-)! God bless you sir :D
I love how calm and confident he is about chemistry. And he is so cute I could just eat him up.
Holy crap thank you Tyler. I'm in Gen Chem II and you've been more helpful than my instructor has been.
I really appreciate your videos. I'm going back to school online and chemistry has not been easy to learn on my own. Your videos are so clear and thought out that I'm finally starting to understand the concepts. Thank you!
you are awesome sir.. :)
Respect.. (y)
Why is this man not my professor?
Tyler, thank you so much. You are amazing for doing this.
Again, thank you Tyler!!
This video is great and a great revision to me, as German schools do this interesting stoichiometry in the first years of chemistry lessons just to ignore it in the later years and instead annoy with electrochemistry and pH and pOH stuff. I miss the good old organic chemistry and redox equations ;(
Thank you! I'm so happy this helped!
Thank you for explaining and uploading :)
does it always has to be hydroxide and nitrogen in basic solution with any given element to balance??..
Anthony okpara As far as I understood this, the hydroxide is necessary for balancing in basic solutions (duh), the nitrogen on the other hand is just an example. You can exchange it with other elements as the crucial part of balancing involves only charges and the hydroxide. Does this answer your question?
okay,
Has anyone else stopped the video and is going thru the comments section just to cross check if other's chemistry teachers are just as bad as theirs?
Yes, my Chem teacher is not awesome.
My major sub is chem and trust me when I say I m failing bad in it . I m hopeless
Artexdirect Artexdirect it will definitely get better. I’m struggling hard too, but it’ll be okay
yeah, for real
My chem teacher is awesome but were in lockdown
This will take 18 mins of your time, yet full of learnings that you can easily absorb bc of how the guy explains it in a simple way. Thank you, Sir.
Great video. I really like that you dont go too fast so people can actually understand.
YOU ARE SERIOUSLY THE BEST !!!!! #CHEMISTRYGOD..HAHA!!! BUT THAT'S TRUE
you teach me more than my actual teacher lmao
The monster couldn't have been simplified more than that. Here is a big thank you!
Thank you so much for explaining everything in so much detail. So many people skip over how to balance the electrons specifically and I was very confused. Thank you!!
How can I donate!! I wish to help others learn this way :)
Go to his youtube page. There's a link on the right side of the page where you can donate.
I hate the fact that he stopped making videos
💯 Best of all the 1000+videos available on UA-cam. 👍👍
A million likes from my side..
You’re honestly a blessing!!! Words can’t describe how grateful I am, for your tutorials. Because of your help, I am able to Ace my Chemistry class at my university. You’re lecture’s are 1.0x10^3 =) more helpful than those of my professor. God bless you!!!
I LOVE YOU PROFESSOR DEWITT! no homo tho
Please tell me the Rules to balance Redox Half Reactions.
Please watch the video.
+Tyler DeWitt savage
+shanikhan00 AHAHAHAH
+Gianmarco Iachella straight up savage
dang bruh savage
Thanks from Sweden, my man!
This is the most useful video I can find on UA-cam 😭 Thanks a lot
LOOOL he so smiley it actually made me happy cause i was so mad just how confusing my lesson was.May God bless him
thank you so much you have no idea how much this helps me
Been struggling to understand this, this video helped a lot!!
I. Love. You. Omg. This makes chemistry a lot simpler. Seriously a blessing. Thank you!
