An acid-base buffer is a solution that lessens the change in [H3O+] that Example: addition of sodium acetate (CH3COONa or NaAc) to acetic acid ( CH3COOH

For example, formic acid (HCOOH) dissociates into [H+] and [COOH-] where the equilibrium con- stant (Ka) for the weak acid can be de- scribed mathematically as:
