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

If the $pKa$ of lactic acid is $5$,then the $pH$ of $0.005 \ M$ calcium lactate solution at $25^{\circ} \ C$ is $........ \times 10^{-1}$ (Nearest integer). The structure of lactic acid is given below:

Calculate the $pH$ of a $1.0 \, M$ ammonium formate solution,given that $K_a = 1 \times 10^{-4}$ and $K_b = 1 \times 10^{-5}$.

The $K_{a}$ for $CH_{3}COOH$ is $1.8 \times 10^{-5}$ and $K_{b}$ for $NH_{4}OH$ is $1.8 \times 10^{-5}$. The $pH$ of ammonium acetate solution will be

Calculate $pH$ and degree of hydrolysis $(h)$ of $0.01 \ M$ $CH_3COONa$ solution. Given: $K_h = 5.6 \times 10^{-10}$.

The dissociation constants of $CH_3COOH$ and $HCN$ are $1.8 \times 10^{-5}$ and $7.2 \times 10^{-10}$ respectively. What is the relationship between the degree of hydrolysis of $KCN$ $(x_1)$ and $CH_3COOK$ $(x_2)$?
