網頁Introduction Buffers are solutions that resist a change in pH when small amounts of acid H3O+or baseOH– are added. Buffers consist of a weak acid and its conjugate base (or a weak base andits conjugate acid). Both components must be present in the solution at approximatelyequal concentration and in substantial amounts.
