An aqueous solution of aluminium sulphate would show

If the $pK_b$ for $CN^-$ is $4.7$ at $25\,^oC$,then the $pH$ of a $0.5\,M \,NaCN$ solution is:

If the dissociation constants of ammonium hydroxide $(NH_4OH)$ and acetic acid $(CH_3COOH)$ are both $1.8 \times 10^{-5}$ and $K_w = 10^{-14}$,what is the degree of hydrolysis of $CH_3COONH_4$?

What is the process called when $CH_3COONa$ is dissolved in water?

Calculate $K_h$ and $pH$ of $0.1 \ M$ $NH_4Cl$ solution. [ $K_w = 1 \times 10^{-14}$,$K_{NH_4OH} = 1.75 \times 10^{-5}$ ]
