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!

Hey
Every time she points to something, and the camera doesn't show what she's pointing at, a fairy dies.
I KNOW RIGHT!!!
I like the way this lady delivers content really really good, i really enjoy watching your lectures Madam ✅
Buffers 11:46
Imagine students who are not in her class seeing her that day. "Wow, what a nasty professor! Her shirt says 'HA! A-.'"
Very nice lecture and easier to understand
I'm wondering though to what extent, and how amphoteric compounds can be used dirrectly as buffers...
Thank u so much Mam..and MIT..
best lectures of you mam...thnkxxx
Thanks ❤️🤍
This is helpful ❤️🤍
I did't see you better❤❤❤

Thank you!
OMG GREAT PPL
👍👍👍👍👍
Great! 😊
Aa jao sab log
Hey
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.
