Assertion : AgCl is more soluble in NH_3 than in water. Reason : Ammonia is more polar than water.

Correct answer: (C) If assertion is true but reason is false.. Solubility of AgCl ( . at 25^° C ) in H_2 O =0.0020 ~g AgCl per litre of H_2 O Solubility of AgCl in NH_3 (at 25^° C ) =14.00 ~g AgCl dissolved per kg of NH_3 Ammonia is less polar than water, as oxygen is more electronegative than nitrogen.

Q43 / 180 · AIIMS 2011 · Chemistry

Assertion : $\mathrm{AgCl}$ is more soluble in $\mathrm{NH}_3$ than in water. Reason : Ammonia is more polar than water.

A
If both assertion and reason are true and reason is the correct explanation of assertion.
B
If both assertion and reason are true but reason is not the correct explanation of assertion.
Correct answer
C
If assertion is true but reason is false.
D
If both assertion and reason are false.

Solution

Solubility of $\mathrm{AgCl}\left(\right.$ at $25^{\circ} \mathrm{C}$ ) in $\mathrm{H}_2 \mathrm{O}$ $=0.0020 \mathrm{~g} \mathrm{AgCl}$ per litre of $\mathrm{H}_2 \mathrm{O}$ Solubility of $\mathrm{AgCl}$ in $\mathrm{NH}_3$ (at $25^{\circ} \mathrm{C}$ ) $=14.00 \mathrm{~g} \mathrm{AgCl}$ dissolved per $\mathrm{kg}$ of $\mathrm{NH}_3$ Ammonia is less polar than water, as oxygen is more electronegative than nitrogen.

Hence, the correct answer is option: 'C'.

Assertion : $\mathrm{AgCl}$ is more soluble in $\mathrm{NH}_3$ than in water. Reason : Ammonia is more polar than water.
