The dissociation constant of a substitue...

The dissociation constant of a substitued benzoic acid at `25^(@)C` is `1.0 xx 10^(-4)`. Find the `pH` of a `0.01M` solution of its sodium salt.

Text Solution

Verified by Experts

The hydrolysis reaction is `A^(-) + H_(2)O rarr AH + OH^(-)`
`K_(h) = K_(w)/K_(a) = 10^(-10)`
`[OH^(-)] = sqrt(K_(h)C) = 10^(-6)`
