Buffer

What is a Buffer solution? A buffer solution is one which maintains its pH fairly constant even upon the addition of small amounts of acid or base. It is often necessary to maintain a certain pH of a solution in laboratory and industrial processes. Buffer solutions help to maintain pH.A buffer solution resists a change
