Question

Balance the redox reaction below under basic conditions. How many total electrons are transferred in the reaction below?

MnO₄^-(aq) + Br^-(aq) à MnO₂(s) + BrO₃^-(aq)

Answer 1

1) first balance the metal or main element other than H or O.

2) In basic condition,add water on that side which has more oxygen and double hydroxide on the other side.

3) balance electrons on required side to balance the electron.

Number of electrons transfer= 6
