An inorganic compound on strong heating gave a blackish brown powder and two oxides of sulphur. The powder was dissolved in HC1 when a yellow solution was obtained which gave a blood red coloured solution with thiocyanide ions. The inorganic compound may be:

An inorganic compound [A] yellowish green in colour loses its water of crystallisation upon heating . When heated furthr, it changes to blackish brown powder [B] and also gives two oxides of sulphure. The power [B] on boiling with hydrochloric acid given a yellowish solution which gives a bloodred colouration on reacting with potassium thiocyanate. The yellow solution is of

A certain inorganic compound (A) on heating loses water of crystallisation. On further heating a blackish brown powder (B) and two oxides of sulphur (C & D) are obtained. The powder (B) on boiling with HCl gives a yellow solution (E). When H_(2)S is passed in (E) a white turbidity (F) and an apple green solution (G) is obtained. The solution (E) on treatment with thiocyanate ion gives blood red compound (H). Identify (A) to (H).

When Cu powder is heated with CuCl_(2) solution, the compound obtained is

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) .

An inorganic compound (A) gave the following reactions: The compound on heating gave a residue and a gaseous mixture of No_2 " and " O_(2+) The aqueous solution of (A) gave a white,precipitate with sodiụm chloride solution. The precipitate dissolves in NH_4OH : The compound (A) is:
