Verified by Experts

These observations suggest that the substance (A) is sulphur (S), the gas (B) is nitrogen dioxide `(NO_(2))` , compound (C) is sodium thiosulphute `(Na_(2)S_(2)O_(3))` and the gase (D) is sulphur dioxide `(SO_(2))` . The reaction are as follows :
`Na_(2)S_(2)O_(3)(C) + H_(2)SO_(4) to Na_(2)SO_(4) + SO_(3)(D) + S+underset("(turbidity)")(H_(2)O) S+O_(2) to SO_(2)`
