To a solution containing Ca^(2+), Ag^(+)...

To a solution containing `Ca^(2+)`, `Ag^(+)`, `Cu^+` and `K^+` `2` M `HCl` is added when a white ppt. `(A)` is obtained. After filtration `H_(2)S` is passed through the filtrate, a black ppt. `(B)` is formed. On removing `(B)` by filtration it gave white ppt. `(C)` with conc. `Na_2CO_3` solution. Identify `(A), (B)` and `(C)`.
