Balancing Redox Reaction Using Oxidation-Number-Change Method
One way to balance redox reactions is by keeping track electron transfer, by using the oxidation numbers of each of the atoms. For the oxidation-number-change method, start with the unbalanced skeleton equation.
Step 1: Assign oxidation numbers to each of the atoms in the equation and write the numbers above the atom.
Step 2: Identify the atoms that are oxidized and those that are reduced.
Step 3: Use a line to connect the atoms that are undergoing a change in oxidation number.
Step 4: Use coefficients to make the total increase in oxidation number equal to the total decrease in oxidation number.
Step 5: Check the balancing for both atoms and charge.
