Question
What are buffer solutions ? Give anexample of a basic buffer solution.
Solution
Buffer solutions are solutions that resist changes in pH when small amounts of acid or base are added to them. They are made up of a weak acid and its conjugate base, or a weak base and its conjugate acid. The weak acid or base can react with any added acid or base, preventing a significant change in pH.
An example of a basic buffer solution is a mixture of ammonia (NH3) and ammonium chloride (NH4Cl). Ammonia acts as a weak base, while ammonium chloride acts as its conjugate acid. When a small amount of acid is added to this buffer solution, the ammonium chloride will react with the acid, preventing a large change in pH.
