1.

When Cl_(2) gas is passed intoa mixturecontaining Br^(Θ) and I^(Θ) and CHCI_(3),I_(2) (voilet ) firstappear CHCI_(3) layer.

Answer»


Solution :Reducingpower of `I^(Theta) gt BI^(Theta) GTCI^(Theta) gt I^(Theta)`
`21^(Theta) + CI_(2) RARR 2CI^(Theta) + I_(2)`
`2Hi^(Theta) + CI_(2) rarr 2CI^(Theta) + Bi_(2)`
Thus `I_(2)` is FORMED in precipitate of `Bi_(2)` andgiven violetcolour in `CHCI_(2)` hencetrue
