Which of the following salt undergoes anionic hydrolysis ?
Options
- ACuSO ₄
- BNa ₂ CO ₃
- CNH ₄ Cl
- DFeCl ₃
Correct answer
B. Na ₂ CO ₃
Step-by-step solution
Anionic hydrolysis occurs in salts formed by the neutralization of a strong base and a weak acid. CuSO ₄ is a salt of a weak base ( Cu(OH) ₂ ) and a strong acid ( H ₂ SO ₄ ). It undergoes cationic hydrolysis. Na ₂ CO ₃ is a salt of a strong base ( NaOH ) and a weak acid ( H ₂ CO ₃ ). The carbonate ion ( CO ₃²⁻ ) undergoes anionic hydrolysis to produce OH ^- ions: CO ₃²⁻ + H ₂ O HCO ₃^- + OH ^- . NH ₄ Cl is a salt of a weak base ( NH ₄ OH ) and a strong acid ( HCl ). It undergoes cationic hydrolysis. FeCl ₃ is a sal
