WebBuffers are solutions that resist a change in pH on dilution or on addition of small amounts of acids or alkali. A lot of biological and chemical reactions need a constant pH for the reaction to proceed. Buffers are extremely useful in these systems to maintain the pH at a constant value. This does not mean that the pH of buffers does not change. WebBuffer is defined as the solution of reserve acidity or alkalinity which resists a change of pH after the addition of a small amount of acid or alkali. A constant pH is what is used to carry out many chemical reactions. There are many systems that …
