How to Write and Balance Net Ionic Equations
Вставка
- Опубліковано 5 сер 2024
- Writing and balancing net ionic equations can be challenging but if you carefully follow the correct steps you will be successful. In many ways it is just an extension of balancing molecular (regular) equations except with net ionic equations we take into account the charge on ions.
The general steps for writing net ionic equations are:
1. Write the balanced molecular equation.
2. Write the state (s, l, g, aq) for each substance.
3. Split strong electrolytes into ions (the complete ionic equation).
4. Cross out the spectator ions on both sides of complete ionic equation.
5. Write the remaining substances as the net ionic equation.
-----
Molecular Equation: The equation we are given without anything broken apart into ions.
Total or Complete: all strong electrolytes are broken apart into ions. We don’t break apart solids, liquids, gases, or weak electrolyte.
Net Ionic: What is left after we cancel out the ions that appear on both sides of the Complete Ionic Equation. These are called Spectator Ions.
-----
Note that not all equations are net ionic equations. For example, H2 + O2 = H2O is not a net ionic equation. The H2 and O2 are gases and don’t split apart into ions. Water is a liquid that stays bonded and doesn’t dissociate into ions (actually it does a little bit, and this is important, but not something we consider in writing and balancing net ionic equations).
Imagine spending an hour on this , within 10 mins with this video , I understood the method ... FINALLY ARGGGGGGGGG THANKS SO SO SO MUCH
You're welcome!
Which grade are you in?
Right? Haha
This is the one thing I haven't been able to wrap my head around for chemistry, no matter how much people explain it to me but seeing this makes complete sense. Thank you.
Random teachers on the internet>>>my real teacher
This man is an angel. I could not understand this cuz my chem teacher fails at teaching one thing for literal months. Found this video a day before my test, thank you so much
ohhh i didn’t get this at ALL when my chemistry teacher explained it! i get it now!! thank you 🙏☺️
Glad it helped!
I wonder if you were distracted in school. Who was sitting next to you? ;)

God bless you bro I just spent 3 hours trying to find out what it meant and with ur video, understood it withing 6 minutes, I hope your pillows are cold and your charger works at any angle.
Mr. Breslyn, I swear you are the only force putting me through this chem class I'm taking. You are the best!!!
I know this was 3 years ago but the fact that this dude’s video is sooo helpful thank u so much this helped me so much. Definitely subscribing 💗
my teacher's lecture was twice as long as this video and yet you still taught me more bless up
really thanks u from my heart
Thank you so much! I'm currently trying to get today's lecture and couldn't quite figure it out until I watched this video. Great explanation.
Thanks! What really helped me from this video that no other explanation has before: you matched the visual of the precipitate with the AgCl. Sometimes when I do equations, everything becomes really abstract and I actually forget that it's a reaction instead of an equation. Your editing, step by step explanation, and visualization helps me grasp the concept. :)
Also, I really appreciate the clear step by step summary in the description below the video!
Thanks for the kind words! I put a lot of effort into this video so it is great to hear it is helping.
wow this was very well explained! i was really getting fustrated on this topic becuz i couldnt undertand what to do but u just made it soooo simplee thank you so much!
This video really helped me as I have a test on this as well as balancing equations tomorrow and my teacher didn't really explain how to work it out but this video did thanks
Thank you so much for these I’m actually understanding chemistry for once😭❤️
its simple and precise. Easy to understand.
Thank u very much!
Am so amazed by your explanations.
I understand more than what I've learned
My teacher explained this in a very confusing way and I'm so glad I looked this video up, so now I don't have to burn my brain out trying to figure out what I'm supposed to do ...THANK YOU!
Glad it helped!
why is watching a video on youtube easier to understand than being in a classroom for an hour. Thank you
thank you for getting me through chem I,II, and III❤
Thank you ! Solid never dissolves but the aq NaNO3 splits and dissolves completely (since it's a direct reaction and not the two arrows in the middle of the reaction that means that it is reversible [sorry my english isn't my first language])so they're spectators ions (since they didn't change) and these specators aren't affecting that much
This was a very informative video, thank you 👍🏿
You. Saved. My. Life.
Thank you.
THANK YOU SO MUCH!!! the visuals and way you described it helped so much!!!
Glad it helped!
Thank you alot for this explanation it's amazing...but I didn't get how to know the solubility of a compound and the physical state for it
Thank you, sir, 🙏🏻 that's truly helpful
thank you so much this helped me a TON
Glad it helped!
this video helped me so much with my homework, so glad there are people making videos like these on youtube
You are most welcome!
Very clear and helpful! Thank you :)
Glad it was helpful!!
OMG, YOU THE BEST!!!!
where can I find the solubility chart that you mentioned in the video?
Appricated a lot🙏❤️
You are a blessing
this video helped me a lot
Much more thanks its very HELPFULL
Thank you for explaining this. You are a saint among men.
Happy to help!
This video really helped
OMG this helped me so much
This taught me more then my chemistry teacher did in 2 weeks
thankk you so much, respect.
you're a godsend
I couldnt get it but this made it click. Thanks!
You are the best
It's been 2 years and he's still helping us
2 years for u, 4 years for us

Thank you very much it really helped me ♥️♥️💋
You're welcome 😊
Thank GOD
what is the ionic equation of FeSO4 + KMnO4 + H2SO4 = Fe2(SO4)3 + MnSO4 + K2SO4 + H2O
Thank you.Understood it🙂
Most welcome 😊
thank u very much this helps me very much 😭
You're welcome 😊
thanks
Thank you!!!!!!!!!!!!!!!!!!!!!!
You're welcome!
Thanks!
Wow, thank you! You are the first person to use Super Thanks on my channel. It is most appreciated!
Isn't it amazing? Students from all over the world, from different countries and cultures, are united here, in the comment section of Wayne Breslyn's videos, all because of our inability to comprehend chemistry.
I'll have to say that it is very interesting for me as a teacher and scientist to be interacting with people from all over the world. The ability to do so is rather amazing, indeed!
@@wbreslyn yes, thank you for doing what you do>
Thank you the six minutes was worth
That is good to hear!
love yah!
My chem teacher teaches as fast as a cheetah.. Your videos help me a lot🙏
No problem! 🐈
Your videos help me in chemistry
Excellent!
you are great holy God i love you thank you
Tq Sir 😤
Thanks soooo much.
Welcome!
Thank you
Welcome!
i love you :(
H2O2 + MgSO3 = MgSO4 + H2O
Net ionic equation....?
you're doing god's work
he really is
I just learned more in 6 minutes then in 6 hours of class
Glad I could help!
How to state aq gas solid
Excellent
But slow speed
Thanks!
Yours way only understands me
@@wbreslyn your are a great teacher
Which one is lose or gain between positive and negative ion
Positive ions have lost an electrons. Since electrons are negative when you lose on the atom becomes positive. The atom getting an electron gains a negative charge and becomes negative.
Now I can understand chemistry better
Excellent!
someone tell me why I need to take a chemistry class for a computer science degree
May God bless your soul
Thanks! Hey, you might find my new guide on net ionic equations on my website helpful as well! www.Breslyn.org
Bless
Thanks!
where's the video for help in solubility

@@wbreslyn Thanks Doc.
King
you sound like Kevin Conroy's Bruce Wayne (BTAS)
My first name is actually Wayne so that makes sense.
HOLY
Don’t you have to balance the equation first
who else doing 'mastering chemistry' here lol
Maybe I don’t hate Chemistry.
Exactly.... It's just some people make it difficult to understand
I just realized how terrible Aleks is at teaching chemistry content...
