A coloured solution of a salt gives following reactions: I. It gives white precipitate with sodium hydroxide which becomes brown on exposure to air. II. It gives white precipitate with ammonia solution which is soluble in ammonium salts. III. Its acidified solution contanining a few drops of dilute AgNO_(3) on boiling with ammonium peroxodisulphate gives a reddish violet solution. The cation of the salt is:

Silver nitrate solution when added to a colourless aqueous solution E forms a white precipitate which dissolves in excess of E. if the white precipitate is heated with water it turs black and the supernatant solution gives a white precipitate with acidified barium nitrate solution. Therefore, E is:
