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

(a) On bolining a mineral (A) with Na_2CO_(3) solution, a white precipirtate (B) is formed. (b) The precipitate is fitered and the filtrate contains two conpounds ( C) and (D) . The componds ( C) is removed by crystallisation and when CO_(2) is passed through the mother liquor left, (D) changes to ( C) . ( c) On strongly heating ( C) , two compounds (D) and ( E) are formed. (d) (E) on heating with cobalt oxide provides blue-coloured substance (F) . Identify (A) to (F) and give chemical reaction for (a) to (d) .
