Detailed explanation-1: -Buffers are chemicals that minimize changes to the pH of a solution when acids or bases are added. (Think of them as pH insulators–they slow any change in pH). Buffers can take up extra hydrogen ions, or release them when the number of H+ ions in the solution drops.
Detailed explanation-2: -This mechanism involves a buffer, a solution that resists dramatic changes in pH. Buffers do so by being composed of certain pairs of solutes: either a weak acid plus a salt derived from that weak acid, or a weak base plus a salt of that weak base.
Detailed explanation-3: -Buffers are solutions that resist changes in pH, upon addition of small amounts of acid or base. The can do this because they contain an acidic component, HA, to neutralize OH-ions, and a basic component, A-, to neutralize H+ ions. Since Ka is a constant, the [H+] will depend directly on the ratio of [HA]/[A-].
