The aqueous solution of $FeCl_3$ is acidic due to

Which of the following salts undergoes anionic hydrolysis?

Which of the following salts will not undergo hydrolysis?

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

At $25 \ ^\circ C$,a weak acid $HX$ has the dissociation constant $K_a = 1 \times 10^{-5}$. It forms a salt $NaX$ on reaction with an alkali. The percentage of degree of hydrolysis of a $0.1 \ M$ solution of $NaX$ is $..... \%$.

The compound whose $0.1 \, M$ solution is basic is
