A compound (A) is greenish crystalline salt, which gave the following results.
i) Addition of `BaCl_(2)` solution to the solution of (A) results in the formation of 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. HCI to give a yellow solution (F).
iv) With H2S the solution (F) yields a pale yellow ppt. (G) which when filtered, leaves a greenish filtrate (H).
v) Solution (F) on treatment with thiocynaate ions gives blood red coloured compound (I).
