It's really hard to believe that such great teachers exist in this broken education system. Ma'am, you are just awesome! Thank you for making these videos.
Thank you - I appreciate the praise. Sadly, the broken education system drove me out of it and I work in industry now. But I did enjoy the teaching part of teaching!
Since I'm teaching from Harris, Quantitative Chemical Analysis, this is pretty much exactly the lecture I had planned to give to my students as I move to online course content.
The form will change based on the solution pH. When the pH is more basic then you have more of the active Y 4- form. But essentially the disodium means 2 Na+ were needed to charge balance the EDTA (so the EDTA is in Y 2- form). However, once in the pH of the solution in the receiving flask of the titration, the EDTA undergoes equilibrium to be in its form at the reacting pH in your Erlenmeyer flask. In most (all?) EDTA titrations you use a buffer or acid or base to control the reaction pH. I hope this was a clear enough explanation.
You explained it so much better than the book, thank you so much!
This really helped thank you! basically summed up an hour and a half lecture in 20 min.
Great breakdown of a complex topic! Thank you for the video.
Well organized and clearly explained. Learned lot stuff in EDTA.
Thank you very much.
That was sooo good, thank you!
This is fantastic!!! Thank you!!

THANK YOU. THIS ACTUALLY HELPS!
Such a good lecturer, wow!
Very nice and helpful! thank you very much for your efforts!
Clearly explained working of EDTA, thanks 😊
Thank you for this wonderful presentation:)
Very nice explanation! Thanks.
clear explanation, thank you for the video.
Usefull video! You were so clear. Thank you for your work.
Amazing explanation, thank you very much
This is an excellent presentation and very useful. Thank you so much for your hard work.
so so helpfull i have a final tomorrow and i was worried sick about this section of the exam now i fell much better.thank you so much
thanks!! it's so helpful!
Thankyou so much for the video
I fucking love this lady. Thank you! E100000000000
Tfw the organic chemistry tutor didn't make a video on it so you're watching someone else now ;-;
Exactly
Hi😅
Thanks 🙏🏻
excellent
IS murexide Triprotic?
is EDTA in an acidic form or in basic form of disodium when it is used in titration?

EDTA Formula is : Formula: C10 H16 N2 O8
Hi.
Your formula for EDTA in wrong. EDTA has 4 acidic H not 6!
There are many mistakes in the vid.
No....we don't love tables
