Question

Statement I : The aqueous solution of a salt of strong base and weak acid has pH less than 7 . Statement II : Cationic hydrolysis gives a solution of $\mathrm{pH}>7$.

Professor PC Thomas Classes · Answer

(c) : Solution of salt of strong base and weak acid has pH more than 7 because anionic hydrolysis takes place. \ $ \mathrm{CH}_3 \mathrm{COONa}_{(a q)}+\mathrm{H}_2 \mathrm{O} ightarrow \mathrm{CH}_3 \mathrm{COO}_{(a q)}^{-}+\mathrm{Na}_{(a q)}^{+} \  \mathrm{CH}_3 \mathrm{COO}_{(a q)}^{-}+\mathrm{H}_2 \mathrm{O} ightleftharpoons \mathrm{CH}_3 \mathrm{COOH}_{(a q)}+\mathrm{OH}_{(a q)}^{-} $ \ Solution is basic.
