(A) Potassium cyanide $(KCN)$ is a salt of a strong base $(KOH)$ and a weak acid $(HCN)$.When dissolved in water,it undergoes anionic hydrolysis:$CN^{-} + H_2O \rightleftharpoons HCN + OH^{-}$Due to the production of $OH^{-}$ ions,the concentration of hydroxide ions in the solution increases.Consequently,the $pH$ of the solution increases,making it basic.
