The aqueous solution of $AlCl_3$ is:

On dilution,the $pH$ of $CH_3COONa$ solution:

For the reaction $HCOO^{-} + H_2O \rightleftharpoons HCOOH + OH^{-}$,which of the following relations is correct?

If the dissociation constant of $HCN$ is $1.3 \times 10^{-9}$ and $K_w = 1 \times 10^{-14}$,then the $pH$ and percentage of hydrolysis of $\frac{N}{100} \ KCN$ are respectively:

Which of the following relations is correct for a solution of $CH_3COONH_4$ salt? Concentration $0.001 \ M$,degree of hydrolysis $x_1$; Concentration $0.002 \ M$,degree of hydrolysis $x_2$.

The degree of hydrolysis of a salt of weak acid and weak base in its $0.1 \, M$ solution is found to be $50 \%$. If the molarity of the solution is $0.2 \, M$,the percentage hydrolysis of the salt should be $...... \%$.
