will you please tell me the difference between a buffer & hydrolysis

Hi Kushal,

A buffer is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. It has the property that the pH of the solution changes very little when a small amount of acid or base is added to it.

Hydrolysis is a chemical process in which a molecule is cleaved into two parts by the addition of a molecule of water. One fragment of the parent molecule gains a hydrogen ion (H⁺) . The other group collects the remaining hydroxyl group (OH⁻).
