Do you expect different products in solution when aluminium $(III)$ chloride and potassium chloride are treated separately with $(i)$ normal water,$(ii)$ acidified water,and $(iii)$ alkaline water? Write equations wherever necessary.

Repeated use of which of the following fertilizers would increase the acidity of the soil?

An aqueous solution of $K_2SO_4$ will be ....

$A$ salt $'X'$ is soluble in water and has a $pH = 7$. However,the resulting solution exhibits alkaline properties. Then the salt is formed from -

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 :
