Question
Explain the types of buffer solutions.
✓
Answer
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 $CH_3COOH$ and its salt such as $CH_3COONa$ 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 $NH_4OH$ and its salt such as $NH_4Cl$ is a basic buffer solution.
