Balance each of the following redox reactions occurring in basic solution. mno−4(aq)+br−(aq)→mno2(s)+bro−3(aq) express your answer as a chemical equation. identify all of the phases in your answer.

Answer : The balanced chemical equation is,

Explanation :

Rules for the balanced chemical equation in basic solution are :

First we have to write into the two half-reactions.Now balance the main atoms in the reaction.Now balance the hydrogen and oxygen atoms on both the sides of the reaction.If the oxygen atoms are not balanced on both the sides then adding water molecules at that side where the more number of oxygen are present.If the hydrogen atoms are not balanced on both the sides then adding hydroxide ion at that side where the less number of hydrogen are present.Now balance the charge.

The half reactions in the basic solution are :

Reduction : ......(1)

Oxidation :  .......(2)

Now multiply the equation (1) by 2 and then added both equation, we get the balanced redox reaction.

The balanced chemical equation in a basic solution will be,
