$A$ weak acid with $pK_a$ $5.9$ and a weak base with $pK_b$ $5.8$ are mixed in equal proportions. The $pH$ of the resulting solution is:

The hydrolysis reaction $A^{-} + H_2O \rightleftharpoons HA + OH^{-}$ indicates that the salt is formed from:

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

The $pK_a$ of a weak acid,benzoic acid and $pK_b$ of a weak base,ammonium hydroxide are $4.25$ and $4.75$ respectively. Then the $pH$ of $0.1 \ M$ solution of ammonium benzoate will be

The degree of hydrolysis of a salt of weak acid and weak base in its $0.1 \, M$ solution is found to be $50 \%$. If the molarity of the solution is $0.2 \, M$,the percentage hydrolysis of the salt should be $...... \%$.

Which of the following $0.1 \ M$ solutions of compounds will be basic in nature?
