What should be the degree of hydrolysis of $0.01 \ M$ Lithium formate solution at $25 \ ^oC$,if $K_h = 3.175 \times 10^{-5}$?

Ionization constants for $CH_3COOH$ and $HCN$ are respectively $1.8 \times 10^{-5}$ and $7.2 \times 10^{-10}$. The degree of hydrolysis of $0.1 \ M \ KCN$ $(h_1)$ and $0.1 \ M \ CH_3COOK$ $(h_2)$ follows the order :

An aqueous solution of aluminum chloride is acidic due to $........$.

Why is the $pH$ of an aqueous solution of copper sulphate less than $7$?

In a solution of sodium acetate,the concentration of $CH_3COOH$ is equal to which of the following?
