Question

Which of the following salts undergoes anionic hydrolysis?

• A. $CuS{O}_4$
  
• B. $N{H}_{4}Cl$
  
• C. $AlC{l}_3$
  
• D. $K_{2}C{O}_3$
  

Answer 1

The correct option is D $K_{2}C{O}_3$


The salt formed by neutralization of weak acid and strong base undergoes anionic hydrolysis.
(A)$CuS{O}_4$
Base : $Cu(OH{)}_2$ - weak base
Acid : $H_{2}S{O}_4$ - strong acid
(B) $N{H}_{4}Cl$
Base : $N{H}_{4}OH$ - weak base
Acid : $HCl$ - strong acid
(C) $AlC{l}_3$
Base : $Al(OH{)}_3$ - weak base
Acid : $HCl$ - strong acid
(D) $K_{2}C{O}_3$
Base : $KOH$ - strong base
Acid : $H_{2}C{O}_3$ - weak acid
So, option (D) is correct.
