Question

In an aqueous solution of $N{H}_{4}Cl$
A) Anionic Hydrolysis takes Place
B) $p^H$ of the solution is greater than 7
C) It turns red litmus to blue
D)$K_h=\frac{K_w}{K_a}$

• A. A and D are correct
• B. All are correct
• C. B and C are correct
• D. All are wrong

Answer 1

Answer: (D)

All are wrong

A) wrong Hcl is a strong acid , therefore
Cl will not hydrolysis
B) wrong $N{H}_4^{+}$ will hydrolysis
$N{H}_4^{+}+H_{2}O\to N{H}_{4}OH+H^{+}$
$\therefore$ acidic solution pH<7
C) Acidic solution turns blue litmus to red, thus C is wrong.
D) $k_n=\frac{kw}{k_n}\therefore wrong$
