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

Buffer Solutions Examples For example, a mixture of acetic acid and sodium acetate acts as a buffer solution with a pH of about 4 75 Alkaline buffers, on the
