An aqueous solution of aluminium sulphate would show

Which of the following aqueous solutions will have the highest $pH$?

The dissociation constant of a substituted benzoic acid at $25^{\circ}C$ is $1.0 \times 10^{-4}$. The $pH$ of a $0.01 \ M$ solution of its sodium salt is

The hydrolysis constant $(K_h)$ of $CH_3COONH_4$ is proportional to which of the following?

When $C_6H_5NH_3^+ Cl^-$ salt is dissolved in water,it undergoes hydrolysis. Find the equilibrium constant of the hydrolysis reaction if the ionization constant of the weak base is $10^{-4}$.

What will be the $pH$ and $\alpha$ (degree of hydrolysis) respectively for the salt $BA$ of $0.1 \ M$ concentration? (Given: $K_a$ for $HA = 10^{-6}$ and $K_b$ for $BOH = 10^{-6}$)
