Calculate
(i) pH of the solution,
(ii) degree of hydrolysis of NaCN,
(iii) hydrolysis constant for a 0.1M NaCN solution at `25^@C. [Given: K_a(HCN) = 4.0xx10^(-10)`

Text Solution

Verified by Experts

Degree of hydrolysis
`=sqrt((k_w)/(K_axxc))=sqrt((10^(-14))/(4xx10^(-10)xx0.1))=0.0158` i.e, 1.85%
