Permanganate ion reacts with bromide ion in basic medium to give manganese dioxide and bromate ion. Write the balanced ionic equation for the reaction.

Text Solution

Verified by Experts

Reduction `2MnO_(4) + 6E^(-) rarr 2MnO_(2)`
Oxidation `Br^(-) rarr BrO_(3)^(-) + 6e^(-)`
Complete redox reaction would be `2MnO_(4)^(-) + Br^(-) + H_(2)O rarr 2MnO_(2) + BrO_(3)^(-) + 2OH^(-)`
