Solution

The correct options are
A Copper sulphate
B Ammonium sulphide
C Ferrous chloride
(i) $F e C l_{2} + N a_{2} C O_{3} ⟶ F e C O_{3} ↓ + 2 N a C l$
(ii) $C u S O_{4} + N a_{2} C O_{3} ⟶ C u C O_{3} ↓ + N a_{2} S O_{4}$
(iii) $(N H_{4})_{2} S + N a_{2} C O_{3} ⟶ (N H_{4})_{2} C O_{3} + N a_{2} S$
