Question

What is buffer solution ? Write any two properties of buffer solution. Derive the formula for calculating the pH for acidic buffer. Write any two examples of simple buffer.

Answer 1

Buffer solution : The solution which resists change in pH on dilution or with the addition of small amounts of acid or alkali is called buffer solution.
Properties of buffer solution

(i) Buffer solution resists change in pH.

(ii) It is used to prepare a buffer solution of particular pH.

pH of Acidic buffer:

Examples of Simple buffer

(i) CH₃COONH₄

(ii) (NH₄)₂CO₃
