Find the pH of a Buffer after adding NaOH

Adding NaOH *increases* the amount of conjugate base in the buffer solution, and also *decreases* the amount of weak acid. This affects the "base over acid" part of the Henderson-Hasselbalch equation ... the part that is Log'ed. So adding a small amount of NaOH will increase the pH of the solution, but not by much.

So when adding bases yo add it to the base in the log and reduce that number from the acid, the opposite for adding acids is the same

Great video! Right when I needed this specific type of question for help :)

If we were to add HCl, would we be adding the moles to the weak acid and subtracting from the conjugate base?

My lecturer has a very long method of doing a problem like the one in this video. Will i still get full marks if i follow your method instead? :)

If you add 1 mL of a solution do you need to re calculate your concentration of conjugate acid and base

[oscarcolin]

Wouldn't you have to find the moles of the acid and base and then subtract the 0.001 from that and then recalculate the concentrations?

What happens when the concentration of the added sodium hydroxide is much higher than the the acid

[localsleepdeprivedmonkey]

Thank you!! but what would happen when you add something like 2M NaOH? do you still take moles or in terms of concentration for the henderson's eqn?

[ARTDEVGRU]

how do you do this if not given the pka?

Lmfao!!!! I can tell you just learned that and wanted to use it!!!;)
