An aqueous solution of Al_(2)(SO_(4))_(3),FeSO_(4) and chrome alum is heated with excess Na_(2)O_(2) . A brown residue and an yellow filtrate are obtained. Discuss.

A metal sulphide A gives gas B with rotten egg smell and a colourless sulphate C, when treated with dil H_2SO_4 . B reacts with K_2Cr_2O_7//H^+ to form D, a white grey element. D burns in oxygen to yield E a colourless gas. If B is added to E, it gives D and a colourless liquid, which turns anhydrous CuSO_4 blue. C gives precipitate with NH_(3(aq)) or NaOH, which dissolves in excess of NaOH
