For a weak acid $HA$,$pK_a = 4.80$. For a weak base $BOH$,$pK_b = 4.78$. What is the $pH$ of an aqueous solution of the salt $BA$?

Which of the following statements is true for an aqueous solution of $CuSO_4$?

Identify the salt that undergoes hydrolysis and forms an acidic solution from the following.

The percentage degree of hydrolysis of a salt of weak acid $(HA)$ and weak base $(BOH)$ in its $0.1 \ M$ solution is found to be $10 \%$. If the molarity of the solution is $0.05 \ M$,the percentage hydrolysis of the salt should be ....... $\%$.

In the hydrolysis of a salt of a weak acid and a strong base,$A^{-} + H_{2}O \rightleftharpoons HA + OH^{-}$,the hydrolysis constant $(K_{h})$ is equal to...

The correct relationship between the hydrolysis constant $(K_h)$ and the dissociation constant $(K_b)$ for $MgCl_2$ is:
