Question

In which of the following salts, only cationic hydrolysis is involved? (A) CH 3 COONH 4 (B) CH 3 COONa (C) NH 4 Cl (D) Na 2 SO 4

Tardigrade Admin · Accepted Answer

NH 4 Cl involved cationic hydrolysis. Salts of strong acids and weak bases form acidic solutions. Dissolution: NH 4 Cl longrightarrow NH 4++ Cl - Hydrolysis: NH 4++ H 2 O leftharpoons NH 3+ H 3 O +

Q. In which of the following salts, only cationic hydrolysis is involved?

$C H_{3} COON H_{4}$

$C H_{3} COON a$

$N H_{4} Cl$

$N a_{2} S O_{4}$

$N H_{4} Cl$ involved cationic hydrolysis.

Salts of strong acids and weak bases form acidic solutions.

Dissolution : $N H_{4} Cl ⟶ N H_{4}^{+} + C l^{-}$

Hydrolysis : $N H_{4}^{+} + H_{2} O ⇌ N H_{3} + H_{3} O^{+}$

NH4​Cl involved cationic hydrolysis. Salts of strong acids and weak bases form acidic solutions. Dissolution : NH4​Cl⟶NH4+​+Cl− Hydrolysis : NH4+​+H2​O⇌NH3​+H3​O+

$C H_{3} COON H_{4}$

$C H_{3} COON a$

$N H_{4} Cl$

$N a_{2} S O_{4}$

$N H_{4} Cl$ involved cationic hydrolysis.

Salts of strong acids and weak bases form acidic solutions.

Dissolution : $N H_{4} Cl ⟶ N H_{4}^{+} + C l^{-}$

Hydrolysis : $N H_{4}^{+} + H_{2} O ⇌ N H_{3} + H_{3} O^{+}$
