The aqueous solution of aluminium chloride $(AlCl_3)$ is acidic due to:

Which of the following is a mixed salt?

Calculate $[H^{+}]$ of a $0.01 \ M$ $A^{+}B^{-}$ salt solution if the $K_a$ of $HB$ is $10^{-12}$.

In which of the following salts,only cationic hydrolysis is involved?

Find the equilibrium constant for the equilibrium reaction:
$HCOO^{-} + H_2O \rightleftharpoons HCOOH + OH^{-}$
Given that the dissociation constant of formic acid is $K_a(HCOOH) = 1.8 \times 10^{-4}$.

The degree of hydrolysis in hydrolytic equilibrium $A^{-} + H_2O \rightleftharpoons HA + OH^{-}$ at salt concentration of $0.001 \ M$ is $(K_a = 1 \times 10^{-5})$
