@@pradeep4791 a titrant is a substance of a KNOWN concentration. That means, the concentration is precalculated. Unfortunately, that was not explained in the video
I don't know how God brought me to your video, but I am so thankful for it. I was freaking out in fear of not knowing what to do in chemistry practical but this showed me everything I needed to know. THANK YOU SO MUCH!!😁😁
Shouldnt the unknown substance always in the burette? Because with indicators apart from phenolphthalein such as Methyl Orange and Thymol Blue it is way easier to see the color changes that indicate its endpoint if the tyrand(HCL) is placed on in the burette and the known is placed in the conical flask first?
Hi Ivan, this is Ravi from Pearson Education. Are you interested to work with us? I am looking for a person who can create lab experiment videos of chemistry and you are pretty good in that. Hoping to listen from you.
The burette and the pipette should have been washed. The burette first with de ionised water and then the solution going into the burette. Secondly, the pipette should have also been washed with the solution going inside of it and the conical flask too. Results wouldn’t be very reliable
Wasn’t the volume of the acid and alkali supposed to be converted to dm^-3? Because the unit of concentration is mol/dm^3
Yes I think you are correct. Pinning this for others to see.
Where should be the acid placed
@@IvanKahl how did you know that the concentration of NaoH was 0.1..?????????
If we're gonna convert both of them won't the units just get cancelled out with no effect on the answer?

7 years later, still helpful. Thank You! :)
Omg I have a chemistry practical tomorrow !!! Thank you this is helpful :)
Ikr ditto i have one too
Me 2
Hello
Lv u bby❣️
U r right jimni
Bro u did a great job🤙🤙
U just saved me from failing in my chemistry practical
Same I was so fucked
I also have chemistry practical which is exactly titration. I'm glad there's this..thanks alot
You are a life saver thank you for clearing my confusion
God bless you brother! you just saved me
Thanks for the help with chemistry
Wow youngest star 🌟 explain well in a simple way where even elementary students can understand, thanks for help and keep up the best work
Thank you so much
I have now gotten a better understanding of titration
thank u very much.. its really very useful
woow thats great i have learnt something
Thank you so much, amazing and helpful video
I love this guys ,🙋🙆
About to do a a titration practical and so far I am hopeful atleast there is the power of Guessing on my side 😂
thank you very much..was helpful
Thank you sir it is very useful
THANKS for explaining step by step..calculations .
Thank you so much ur video is still very useful upto now ❤❤❤
Great job dude
Ang galing🥰🥰
Thank you very much,Sir.
Great experience
It's soo useful
Got a prac test tomorrow, thanks bro.
Pluto!!!
Nice video...really helpful 👍🙂
yes man poli sanam🤣💋
Pinnalla🤣
Super sir I got clarity
Thanks a lot for nice teaching sir
thanks very useful
well explained
thanks for the video

In the exam the exact indicator to use will be given
Thanks Sir very useful
No problem
Very nice ❤❤❤❤
Thank you bro
Quite impressed
Good that was a great help there thank you
Tanx bro 4making me understand how 2 find d concentration
Really I have a chemistry practical tomorrow
I like it I wanted to learn had 👍
thank you sooo much, this video really helped me alot.
Thanks for making this easy
Thank you so much Sir for the explanation... It is too helpful
Sir you are absolutely great i am an indian and I am very thankful to you for making this video
Glad you found it useful!
This is what I was looking for...👍great.
Is the volume of base not supposed to be 25 and not the other way around
Thanks so much
Thanks sir
really helpful
Bro thanks you helped me i was like the worst in titration 7:19
Thanks dud
Do you have to let the air out of the burret before filling like you do with a sep funnel?
Very nice
Hey Ivan.. Thank you 🙏 you saved my life😅😅
thnq sir i got it clearly
ME TOO!
Tqs sir
Thank you so much
I’m still probably going to fail my practical bc the grading of them is ridiculous, but I feel much more prepared now.
it a nice lesson
nice
Very good
5:15 would using a stir bar and stir plate be sufficient? (As opposed to shaking it constantly as seen here)
You could probably make use of a stir bar and stir plate. It shouldn't have any impact on the experiment.
@@IvanKahl yeah thsts what i thought... Was wondering if there was a specific reason you opted not to. Thanks for the reply!
Nice
THANKS calculations too .PLEASE
thankyou
Hi
how can calculate the recovery and purity of silver?
it was a very good video IVAN ; i liked it but it should be a bit faster than it is.
O
How did you transform so smoothly?
Thnx sir
Very helpful
It's a pleasure
Do I not rinse the burette with water first and then with the solution I am using
Thanks bro I have a chemistry practical tomorrow. Tell you how I did after it
Good luck!
Ivan Kahl practical wise i did well but the theory part i messed it up
so it is very useful
I'm glad it helped
Pooja Anil.. OK OK 9061135514
Enx so much
How do you know before hand if the reaction is a strong acid-strong base or weak acid, strong base vice versa?
Hi Ivan, this is Ravi from Pearson Education. Are you interested to work with us? I am looking for a person who can create lab experiment videos of chemistry and you are pretty good in that. Hoping to listen from you.
Thank you very much sir.
👌
Wait ain't you supposed to use pippette for NAOH since its an alkali and use biuret for HCI
I thought so too
Does anybody's hand get tired during the swirling of the conical flask?
Dude I’m also at Reddam and I have a chem prac tomorrow lel
That's awesome! Hope it goes well!
What % of HCL is 0.690M HCL? How do you get the % concentration of HCL using titration? What % does 0.05M HCL relate to in %?
Where we got 0.1 from?
cant you use the mole ratio method
This is acidimatry or not
I love YOU
I have practical tomorrow
What if you were to titrate with 2HNO

How did you know that concentration of NaOH was 0.1..?????
Still relevant 5 years later
Still relevant 6 years later
The burette and the pipette should have been washed. The burette first with de ionised water and then the solution going into the burette. Secondly, the pipette should have also been washed with the solution going inside of it and the conical flask too. Results wouldn’t be very reliable
What's the titration level of NaOH in the solution

Mistake. You are showing a funnel but calling it a conical flask
Are you from Reddam?
I was in Reddam in South Africa. Matriculated in 2016 😁👍🏻
Nice vedio
😀😀😀😀
Thank you
So interesting
wher the PPE?
Hmmm
That was amazing
which school is this ??
Reddam House Bedfordview in South Africa
