HOW TO BALANCE MnO4- + Br- = MnO2 + BrO3- by Oxidation Number Method

HOW TO BALANCE MnO4- + Br- = MnO2 + BrO3- by Oxidation Number Method
Step 1
Assign oxidation number for all the atoms in the given equation.
Step 2
Identify the increase and decrease in oxidation number
Step 3
Multiply using the results of Step 2 on the right hand side and balance the left hand side.
Step 4
Check the charges and add H+ on the appropriate side based on the charges.
Step 5
Add H2O on the appropriate side to balance the H - atoms.
Now all the atoms on the LHS and the RHS will be equal. The charges too will be equal on both the sides.
