gosh I am studying operations management...and this video, initially made for chem, helped me understand ''buffering''

Hello Sarah, Thank you for this awesome video !! Would you be able to cover how to calculate PH of buffer solutions and calculating concentrations of solutions required to prepare a buffer solution of a given pH? I appreciate it :)

sarahh

for god's sake do more videos. your explanation is amazing

You are great. I appreciate and love this. I need to prevent hypoglycemia, and they said to me that I need to get a higher buffer capacity of the brain. How do I do that?

Hello,
So if my options are
a) 0.54M NH3 and 0.54M NH4Cl
b) 0.08M NH3 and 0.12M NH4Cl
C) 0.61M NH3 and 0.87M NH4Cl
D) 0.40M NH3 and 0.46M NH4Cl

my answer is a or c?

I have a question:
Why do we assume that ALL of the added hydroxide ions react with the conjugate acid in the buffer solution? Is it just an approximation? Because to my knowledge, especially according to Le Chatelier’s principle, the system would reverse a change made to it; in other words, some hydroxide ion will be reproduced because the initial HA present in the buffer solution would dissociate into H+ to replace the conjugate acid consumed by the added OH-. Therefore, the pH change would technically be lesser than what was derived from the Henderson-Hasselbach equation.
I am so confused - pls help :(
