The pH of a solution is 5, when the hydroxyl ion concentration is

The pH of human blood in a normal person is approximately

If molarity of NaOH is 3.162 × ${10}^{-3}10^\{-3\}$ M, its pH is

The common ion effect is based on

The ion that cannot be precipitated by both HCl and $H_{2}SH\_2S$ is

The correct representation for solubility product of $Sn{S}_{2}SnS\_2$ is

The solubility product of a salt BA at room temperature is $1.21\times {10}^{-6}1.21\; \backslash times\; 10^\{-6\}$. Its molar solubility is :

Among the following hydroxides, the one which has the lowest value of solubility product at temperature 298 K is,

A solution becomes unsaturated when

0.025 M $C{H}_{3}COOHCH\_3COOH$ is dissociated 9.5%. Hence the pH of the solution is
