Answer»


Solution :A) Red vapours - `CrO_(2)Cl_(2)`, KBr heated with `MnO_(2)` and conc. `H_(2)SO_(4)`
B) NaOH solution is turned yellow by the vapours - `CrO_(2)Cl_(2), MnSO_(4) + NaBiO_(3)` + conc. `HNO_(3)`, KBr heated with `MnO_(2)` and conc. `H_(2)SO_(4)`
C) Purple solution - `MnSO_(4) + NaBiO_(3) + conc. HNO_(3)`, KBr heated with `MnO_(2)` and conc. `H_(2)SO_(4)`
D) A COLOURLESS solution results when the evolved gas is absorbed in an NaOH solution - `[Fe(CN)_(5)NOS]^(4-)`
