In the reaction 3Br(2) + 6CO(3)^(2-) +...

In the reaction
`3Br_(2) + 6CO_(3)^(2-) + 3H_(2)O to 5Br^(-) + 2BrO_(3)^(-)+6HCO_(3)^(-)`

A

Bromine is oxidized and carbonate is reduced

B

Bromine is reduced and water is oxidized

C

Bronine is neither oxidized nor reduced

D

Bromine is both reduced nad oxidized

Text Solution

Verified by Experts

The correct Answer is:
D
`3Br_(2) +6CO_(3)^(2-) + 3H_(2)O to 5Br^(-)+BrO_(3)^(-) + 6HCO_(3)^(-)` oxidation number of `Br_(2)` changes from zero to -1 (in `Br^(-)` ) and + 5 (in `BrO_(3)^(-)`) , hence it is reduced as well as oxidized.
