What is a buffer ?

Such solutions in which pH does not vary with the addition of acids/bases in small quantities. For example, blood

A buffer is a solution that resists changes in its pH when small amounts of acid or base are added. It usually contains a weak acid and its conjugate base (or a weak base and its conjugate acid). The buffer works by neutralizing added acids or bases, maintaining a stable pH.

For example, acetic acid (CH₃COOH) and its conjugate base acetate (CH₃COO⁻) make up a common buffer system. If you add acid, the acetate ions will absorb the extra hydrogen ions (H⁺), and if you add base, the acetic acid will donate hydrogen ions to neutralize the hydroxide ions (OH⁻).

In short, a buffer helps keep the pH of a solution steady even when you add small amounts of acid or base.

A buffer is a solution that helps keep the pH constant, even when small amounts of acid or base are added.

It usually consists of a weak acid and its conjugate base (or a weak base and its conjugate acid), which work together to neutralize changes in the pH.
