A colourless inorganic compound (A) imparts a green colour to flame. Its solution does not give white precipitate with `H_(2)S`. Its solution gives white precipitate with conc. `H_(2)SO_(4)` which is insoluble in dil. `H_(2)SO_(4)`. When it is heated with `K_(2)Cr_(2)O_(7)` and conc. `H_(2)SO_(4)`, a red gas is evolved. The gas when passed through aqueous NaOH solution turns it Yellow. Identify the compound (A) and give chemical reactions.
