Light green compound (A) overset(Delta) ...

Light green compound `(A) overset(Delta) to ` White residue `(B) underset("temp.")overset("High")to C+D+E`
(i) D and E are acidic gases.
(ii) D is passed through `HgCl_(2)` solution to give yellow precipitate.
(iii) When E is passed through water first and then `H_(2)S` is passed, white turbidity is obtained.
(iv) A is water soluble and on addition of `HgCl_(2)` in it, a white precipitate is obtained which does not turn grey on addition of excess solution of A.
The yellow precipitate in the above reaction is

A

mercuric oxide.

B

basic mercury(II) sulphite.

C

basic mercury (II) sulphate.

D
