Question

What is buffer solution? Give an example.

Answer 1

Buffer solution : A buffer solution is one which maintains its pH fairly constant even upon the addition of small amounts of acid or base.
Two common types of bufffer solutions are :
1. a weak acid together with a salt of the same acid with a strong base. These are called acid buffers,
(eg): $C{H}_{3}COOH+C{H}_{3}COONa$
2. a weak base Mid its salt with a strong acid. These are called basic buffers,
(eg) : $N{H}_{4}OH+N{H}_{4}Cl$
