An easier way to approach the acidity or basicity of a salt is to look at the component acid and base that combined to form it. For example NH4Cl is made through ammonia (weak base) and hydrochloric acid (strong acid), so I think of it as the strong acid portion cancelling out the weak base portion, and leaving a bit of "acidity" behind. In the end, ammonium chloride is slightly acidic.
however, simplifying like this often removes the actual conceptual understanding behind the actual mechanism involved. it might be a good way to remember the resulting acidity of a weak base and a strong acid, but it's much more enlightening to understand the mechanism of how the conjugate of the weak base is actually a strong conjugate acid that dissociates hydronium ions, and the conjugate of the strong acid is a weak conjugate base that only dissociates a negligible quantity of hydroxide ions, therefore the net acidity is acidic
Catherine really is the best, so grateful to have her as the lecturer ❤
The best lecture on Buffers I 've ever seen...
And there’s the difference in [insert generic college/university] and MIT lectures... equally about the why compared to the how. Much appreciated!
Every time she points to something, and the camera doesn't show what she's pointing at, a fairy dies.
I KNOW RIGHT!!!

Hey
I like the way this lady delivers content really really good, i really enjoy watching your lectures Madam ✅
Very nice lecture and easier to understand
Thank u so much Mam..and MIT..
I'm wondering though to what extent, and how amphoteric compounds can be used dirrectly as buffers...
Imagine students who are not in her class seeing her that day. "Wow, what a nasty professor! Her shirt says 'HA! A-.'"

Thanks ❤️🤍
best lectures of you mam...thnkxxx
This is helpful ❤️🤍
I did't see you better❤❤❤
Thank you!
OMG GREAT PPL
Great! 😊

Hey
Aa jao sab log
Why do you name chemical elements as if they are letters from the English alphabet? Why c-h but not chlor or n-a instead of Natriy?
Probably, it's common for American education.
it is wrong.
