A compound (A) is greenish crystalline salt which gave the following results `:`
`i)` Addition of `BaCl_(2)` solution to solution of (A) results in the formation of a white ppt. (B), which is insoluble in dil. 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 conc. HCl to give a yellow solution (F).
`iv)` With `H_(2)S`, the solution (F) yields a pale yellow ppt. (G), which when filtered, leaves a greenish filtrate (H).
`v)` Solution (F) on treatment with thiocyanate ions gives blood red coloured compound (I).
