Moreover, the salt (A) on heating with solid K_(2)Cr_(2)O_(7) and concentrated H_(2)SO_(4) produces deep red vapors which dissolve in sodium hydroxide solution forming a yellow solution. This yellow solution gives yellow precipitate with Ba(NO_(3))_(2) solution. On the basis of teh aforesaid characteristic informations answer the following questions: Acidified solution of A, on treatment with KI gives black precipitate F which dissolves in excess of reagent forming the coloured compound G. The chemical composition of F and G are respectively:
