Answer» SOLUTION :Theseobservations suggestthat thesubstance(A) issulphur (S), the gas (B) is nitrogen dioxide`(NO_(2))` , COMPOUND (C) is sodiumthiosulphute`(Na_(2)S_(2)O_(3))`and the gase(D) is sulphur dioxide `(SO_(2))`. The REACTION are as follows : `2Na_(2)underset((C))(S_(2)O_(3)) + underset("(violet)")(I_(2))to Na_(2)underset("colourless solution")(S_(4)O_(6)) + 2NaI` |
