Vedclass · Accepted Answer

$NH_4Cl$

Vedclass · Answer

(C) Salts derived from a weak acid or a weak base undergo hydrolysis in aqueous solution.$NH_4Cl$ is a salt of a strong acid $(HCl)$ and a weak base $(NH_4OH)$,so it undergoes cationic hydrolysis.$Na_2SO_4$ is a salt of a strong acid $(H_2SO_4)$ and a strong base $(NaOH)$,so it does not undergo hydrolysis.$KCl$ is a salt of a strong acid $(HCl)$ and a strong base $(KOH)$,so it does not undergo hydrolysis.$KNO_3$ is a salt of a strong acid $(HNO_3)$ and a strong base $(KOH)$,so it does not undergo hydrolysis.
