A compound `(A)` is greenish crystalline salt, which gave the following reactions.
(i)Addition of `BaCl_(2)` solution to the solution of `(A)` results in the formation of white precipitate `(B)` which is insoluble in dilute `HCl`.
(ii)On heating `(A)`, water vapours and two oxides of sulphur `(C )` and `(D)` are liberated leaving a red brown residue `(E)`.
(iii)`(E)` dissolves in warm concentrated `HCl` to give a yellow solution `(F)`.
(iv)Solution `(F)` on treatment with thiocyanate ions gives blood red coloured compound `(G)`.
Identify the compounds from `(A)` to `(G)`.
