Buffer solutions do not have an unlimited capacity to keep the pH relatively constant (Figure 4.1.34.1.3\PageIndex{3}). If we add so much base to a buffer that the weak acid is exhausted, no more buffering action toward the base is possible.
If they have an unlimited capacity but if you add to much base it removes the buffering, how much base is to much?

A solution of acetic acid (CH3COOHCH3COOH\ce{CH3COOH} and sodium acetate CH3COONaCH3COONa\ce{CH3COONa}) is an example of a buffer that consists of a weak acid and its salt.
In this example is the salt for the weak acid a base?
