$A$ solution of sodium cyanide $(NaCN)$ is . . . . . . .

On combining which of the following anions with $NH_4^{\oplus}$ will the $pH$ of the resulting salt solution be independent of the concentration?

If $0.1 \, M \, CH_3COONa$ undergoes $1 \%$ hydrolysis,then the values of $K_h$,$K_a$ of the acid,and the concentration of $CH_3COOH$ are respectively:

What does the hydrolysis of $AlCl_{3}$ produce?

$NH_4CN$ is a salt of a weak acid $HCN$ $(K_a = 6.2 \times 10^{-10})$ and a weak base $NH_4OH$ $(K_b = 1.8 \times 10^{-5})$. $A$ $1 \ M$ solution of $NH_4CN$ will be:

$A$ solution of sodium chloride in contact with the atmosphere has a $pH$ of about
