Further explanation:
Buffer solution:
These solutions offer resistance to any changes in their pH if strong acid or base is added to them. Buffer solutions are basically aqueous solution consisting of weak acid and its conjugate base.
The alkalinity or acidity of any solution is governed by its pH. pH range varies from 0 to 14. Solutions that have pH less than 7 are acidic in nature, those with pH 7 are neutral and those with pH more than 7 are basic or alkaline in nature.
Categorization of buffer solutions:
Acidic buffer:
These solutions have pH less than 7 and are formed by weak acid and its conjugate base. For example mixture of acetic acid and sodium acetate form acidic buffer.
Basic buffer:
These solutions have pH more than 7 and are formed by weak base and its conjugate acid. For example mixture of ammonium chloride and ammonium hydroxide form basic or alkaline buffer.
Consider
as a base and its sodium salt becomes NaClO.
is strong base so its conjugate acid becomes weak. Since buffer is composed of aqueous solution of weak acid and its conjugate base, NaClO can be used to make buffer.
