AP Chemistry / Unit 8: Acids and Bases
8.10 Buffer Capacity
Notes
Buffer capacity is how much acid or base a buffer can absorb before pH changes a lot. More concentrated buffers have higher capacity.
Practice
Which buffer has the greatest capacity?
Highest equal concentrations.
A buffer with much more HA than $\mathrm{A^-}$ handles added ___ better.
More HA to neutralize $\mathrm{OH^-}$.
A buffer's capacity is exceeded when:
Nothing left to neutralize.
