Which among the following salts is $NOT$ hydrolysed in water?

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 $BOH = 10^{-6}$)

Which of the following salts does not undergo hydrolysis in water?

If the $K_b$ value in the hydrolysis reaction $B^{+} + H_2O \rightleftharpoons BOH + H^{+}$ is $1.0 \times 10^{-6}$,then the hydrolysis constant of the salt would be

When $CuSO_4$ is hydrated,it becomes:

Which of the following has the lowest degree of hydrolysis?
