What will be the degree of hydrolysis of 0.1 M solution of Nax? When a weak acid HX forms a salt NaX on reacting with NaOH and the dissociation constant of HX is `10^(-5)`

Options

A. 0.0001
B. 0.001
C. 1.0E-5
D. 0.0015

Answer

A

Explanation

`NaX+H_2O `h=sqrt((K_W)/(K_a xx c))=sqrt((10^(-14))/(10^-5 xx 10^-1))`
`=sqrt(10^-8)`
`h=10^-4,"percentage"`
`h=10^-4 xx 100 = 0.01 %`
