Assuming that the degree of hydrolysis is small, the pH of 0.1 M solution of sodium acetate ( K _ a =1.0 10⁻⁵ ) will be:

Options

  1. A5.0
  2. B6.0
  3. C8.0
  4. D9.0

Correct answer

D. 9.0

Step-by-step solution

Sodium acetate is a salt of strong base and weak acid. aligned & pH =7+ 1 2 p K_a+ 1 2 c where & p k_a=- K_a=- 10⁻⁵=5 & c = 10⁻¹=-1 & pH =7+ 5 2 - 1 2 =9.0 aligned
