Vedclass · Answer

(C) When a salt containing sulphide ion $(S^{2-})$ is warmed with dilute $H_2SO_4$,hydrogen sulphide $(H_2S)$ gas is evolved: $Na_2S + H_2SO_4 ightarrow Na_2SO_4 + H_2S \uparrow$When this gas is passed over a filter paper dipped in lead acetate solution,it forms lead sulphide $(PbS)$,which is black in colour:$(CH_3COO)_2Pb + H_2S ightarrow PbS (	ext{black}) + 2CH_3COOH$Thus,Statement-$I$ is true.Statement-$II$ is false because the black colour is due to the formation of lead sulphide $(PbS)$,not lead sulphite $(PbSO_3)$.
