Detailed Solution

A) $2 {Bi}^{3 +} + 3 H_{2} S \to {Bi}_{2} S_{3} ↓ (black) + 6 H^{+}$
B) ${Cu}^{2 +} + H_{2} S \to_{}^{} CuS ↓ (black) + 2 H^{+}$ ${Cu}^{2 +} + 2 SC N^{-} \to_{}^{} Cu {(SCN)}_{2} ↓ (black)$ Which on standing slowly changes to white $2 Cu {(SCN)}_{2} \to_{}^{} Cu {(SCN)}_{2} ↓ (black)$ ${Cu}_{2} I_{2}$ is white precipitate and ${Cu}_{2}$ $[Fe {(CN)}_{6}]$ brown precipitate.
(C) $\begin{array}{l} {Zn}^{2 +} + H_{2} S \to ZnS ↓ (white) + 2 H^{+} 2 K^{+} + 2 {[Fe (CN)_{6}]}^{4 -} + 3 {Zn}^{2 +} \to K_{2} {Zn}_{3} {[Fe (CN)_{6}]}_{2} ↓ (white) \\ {ZnI}_{2} \to solube (D) 4 {Ag}^{+} + {[Fe (CN)_{6}]}^{4 -} \to {Ag}_{4} [Fe (CN)_{6}] ↓ (white) \\ {Ag}^{+} + {SCN}^{-} \to AgSCN ↓ (white) {Ag}^{+} + {Cl}^{-} \to AgCl ↓ (white) {Agg}_{2} S ↓ black; AgI ↓ yellow \end{array}$
