(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)`.
