$KClO_4$

Vedclass · Answer

(A) Salts formed from a strong acid and a strong base do not undergo hydrolysis in water because their constituent ions do not react with $H^+$ or $OH^-$ ions to change the $pH$ of the solution.$KClO_4$ is a salt of a strong acid $(HClO_4)$ and a strong base $(KOH)$. Therefore,it dissociates completely into $K^+$ and $ClO_4^-$ ions,which do not react with water.In contrast,$NH_4Cl$ (salt of weak base and strong acid) and $CH_3COONa$ (salt of weak acid and strong base) undergo hydrolysis.
