A pale yellow inorganic compound K is insoluble in hot and dil. HNO_(3) but dissolves in concentrated ammonia solution and compound L is formed, on treatment with dil. HNO_(3) compound L produces a metal cation which gives white precipitate M with hypo solution. when an aqueous solution of (M) is boiled, a black precipitate of (N) is formd which dissolves in hot dil. HNO_(3) and on adding HCl gives a white precipitate. when the compound (K) is heated with concentrated H_(2)SO_(4) and MnO_(2) brown fumes are observed. Q. The compound (K) is:
