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.

Correct answer

C. If assertion is true but reason is false.

Step-by-step solution

Solubility of

\mathrm{AgCl}\left(\right.

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}

\mathrm{NH}_3

(at

25^{\circ} \mathrm{C}

)

=14.00 \mathrm{~g} \mathrm{AgCl}

dissolved per

\mathrm{kg}

\mathrm{NH}_3

Ammonia is less polar than water, as oxygen is more electronegative than nitrogen.
