Question

Which salts undergo hydrolysis? (1) NaCl (2) CH 3 COONa (3) KNO 3 (4) NH 4 Cl (A) 1, 2 and 3 are correct (B) 1 and 2 are correct (C) 2 and 4 are correct (D) 1 and 3 are correct

Tardigrade Admin · Accepted Answer

NaCl and KNO 3 salts do not undergo hydrolysis because they are salts of strong base and strong acid. While CH 3 COONa and NH 4 Cl undergo hydrolysis. CH 3 COONa + H 2 O longrightarrow CH 3 COOH + NaOH NH 4 Cl + H 2 O longrightarrow NH 4 OH + HCl

Q. Which salts undergo hydrolysis?
(1) $N a Cl$
(2) $C H_{3} COON a$
(3) $K N O_{3}$
(4) $N H_{4} Cl$

1, 2 and 3 are correct

1 and 2 are correct

2 and 4 are correct

1 and 3 are correct

$N a Cl$ and $K N O_{3}$ salts do not undergo hydrolysis because they are salts of strong base and strong acid. While $C H_{3} COON a$ and $N H_{4} Cl$ undergo hydrolysis.
$C H_{3} COON a + H_{2} O ⟶ C H_{3} COO H + N a O H$
$N H_{4} Cl + H_{2} O ⟶ N H_{4} O H + H Cl$
