Question

$NH _{4}^{+}$ salts are more soluble in water than the corresponding sodium salts because

• A. $NH _{4}^{+}$ salts are more stable than sodium salts
• B. $NH _{4}^{+}$ salts are more ionic than sodium salts
• C. $Na ^{+}$ ion is solvated by ion-dipole interaction and $NH _{4}^{+}$ ion by $H$ -bonding
• D. $Na ^{+}$ ion is solvated by $H$ -bonding and $NH _{4}{ }^{+}$ ion by ion-dipole interaction

Answer 1

Answer: (C)

Correct answer is (c) $Na ^{+}$ ion is solvated by ion-dipole interaction and $NH _{4}^{+}$ ion by $H$ -bonding
