The aqueous solution of ammonium chloride is

The aqueous solution of copper $(II)$ sulphate is slowly hydrolysed forming basic copper sulphate whose chemical composition is

$A$ $0.02 \ M$ solution of pyridinium hydrochloride has $pH = 3.44$. Calculate the ionization constant of pyridine.

The $pH$ of an aqueous solution of $CH_3COONa$ of concentration $C \ M$ is given by:

If the base ionization constant $(K_b)$ of hydrazine $(N_2H_4)$ is $9.6 \times 10^{-9}$,what is the percentage of hydrolysis of a $0.1 \ M$ solution of the salt $N_2H_5Cl$?

An aqueous solution of $CuSO_4$ will be:
