HX is a weak acid K a = 1 0 - 5 . It forms a salt NaX [0.1 M (aq)] on reacting with aqueous caustic soda solution. The percentage of hydrolysis of NaX is 0.01 × n % , where n is

Correct answer

1

Step-by-step solution

For a salt of a weak acid and strong base degree of hydrolysis is given as h = K w K a . C = 1 0 - 14 0.1 × 1 0 - 5 = 1 0 - 4 % of hydrolysis = 100 × 1 0 - 4 = 0.01 %
