Weak acids and bases buffers

[lha08]

Homework Statement

I'm a little confused, let's say i do a titration curve for a weak acid, at some point there's a buffering range near the pKa. Like i know that if we add a strong base like NaOH to acetic acid in a water solvent, then the OH- will combine with the H+ (hydronium ion) which will shift the equilibrium towards the acetate ion and hydronium ion. But will a different process occur when we add the OH- in the buffering region? Like in my book, it says that it will react with the acetic acid which will form the acetate ion...but i just don't see why this occurs differently then when the OH- reacted with the hydronium ion...
any help/clearing up would be much appreciated

It is not much different - in both cases it is like H⁺ reacting with OH^-. However, in the solution of acetic acid there is - like - a lot of undissociated acetic acid, usually much more than H⁺. Hence we say OH^- reacts with acetic acid, not H⁺.
