MHT CET Chemistry Question (2026) — Solution

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 _3^ 2- ) undergoes anionic hydrolysis to produce OH ^- ions: CO _3^ 2- + 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 salt of a weak base ( Fe(OH) _3) and a strong acid ( HCl ). It undergoes cationic hydrolysis. Thus, Na _2 CO _3 undergoes anionic hydrolysis. Answer: Na _2 CO _3
