Question

Explain the types of buffer solutions.

Answer in Brief
Advertisements

Solution

There are two types of buffer solutions:

  1. 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.
  2. 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.
