A white precipitate (X) is formed when a mineral (A) is boiled with Na_(2)CO_(3) solution. The precipitate is filtered and filtrate contains two compound (Y) and (Z). The compound (Y) is removed by crystallization and when CO_(2) is passed through the filtrate obtained after crystallization, then (Z) changed to (Y) . When compound (Y) is heated, it gives two compounds (Z) and (T). Compound (T) on heating with cobalt oxide produces blue coloured substance (S) The compound (Y) in the filtrate when (A) is boiled with Na_(2)CO_(3) is
