Question
Explain the types of buffer solutions.
Solution
There are two types of buffer solutions:
- Acidic buffer:
A solution containing a weak acid and its salts with strong base is called an acidic buffer solution. It maintains an acidic pH.
e.g. A solution containing weak acid such as CH3COOH and its salt such as CH3COONa is an acidic buffer solution. - Basic buffer:
A solution containing a weak base and its salt with strong acid is the basic buffer solution. It maintains an alkaline pH.
e.g. A solution containing a weak base such as NH4OH and its salt such as NH4Cl is a basic buffer solution.
