A liquid (A) is treated with Na(2) CO(3)...

A liquid (A) is treated with `Na_(2) CO_(3)` solution. A mixture of two salts (B ) and ( C ) are product in the solution. The mixture on acidification with sulphuric acid and distillation produces the liquid (A ) again.
Which of the following Halogen molecule can have Reddish brown colour ?

A

`F_(2)`

B

`Br_(2)`

C

`Cl_(2)`

D

`I_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Halogen molecule can have reddish brown colour is `Br_(2)`.
`underset("(X)")(CaOCl_(2))+ 2KI + 2HCl rarr CaCl_(2) + 2KCl + H_(2) O +I_(2)`
`CaOCl_(2) + 2KI + 2HCl rarr CaCl_(2) + 2KCl + H_(2) O + I_(2) , CaOCl_(2) + CO_(2) rarr CaCO_(3) + Cl_(2)`
