Question

Calculate degree of hydrolysis of a salt of aniline and acetic acid in 0.1 M solution. K_a(CH₃COOH) = 1.8 x 10^–5, K_b (C₆H₅NH₂) = 4.6 x 10^–10

(a) 0.432 

(b) 1.2

(c) 0.523 

(d) None of these

Answer 1

Correct option: (c) 0.523

Explanation: 

Since aniline and acetic acid both are weak electrolytes, we have

This value of ‘x’ being greater than 1 is insignificant. So equation (II) has to be considered. The above equation may now be written as
