If both the Assertion and Reason are incorrect.

Vedclass · Answer

(D) Antimony sulphide $(Sb_2S_3)$ is soluble in yellow ammonium sulphide $( (NH_4)_2S_x )$ to form soluble ammonium thioantimonate $( (NH_4)_3SbS_4 )$.The chemical reaction is: $Sb_2S_3 + 3(NH_4)_2S + 2S \longrightarrow 2(NH_4)_3SbS_4$.Since $Sb_2S_3$ is soluble,the Assertion is false.The common ion effect due to $S^{2-}$ ions would generally decrease solubility,but it is not the reason for the behavior of $Sb_2S_3$ in this context,and the premise of the Assertion itself is incorrect. Thus,both the Assertion and the Reason are incorrect.

Assertion : $Sb_2S_3$ is not soluble in yellow ammonium sulphide. Reason : The common ion effect due to $S^{2-}$ ions reduces the solubility of $Sb_2S_3$.
