Balancing REDOX reactions in acidic solution

1. Balancing REDOX reactions ACIDIC SOLUTION

2. Consider the following unbalanced reaction:

3. STEP 1: DIVIDE THE REACTION INTO HALF REACTIONS

4. STEP 2: BALANCE THE ELEMENTS OTHER THAN H AND O Fortunately, all atoms other than H and O are already balanced, so we can move on to the next step.

5. STEP 3: BALANCE THE O ATOMS BY ADDING H2O

6. STEP 4: BALANCE THE H ATOMS BY ADDING H+

7. STEP 5: BALANCE THE CHARGES BY ADDING “ e-”

8. STEP 6: ADD THE HALF REACTIONS AND SIMPLIFY

9. CARRYING THIS OUT, WE GET:

10. Now we can add the two reactions, and we notice that the electrons on both sides cancel out.

11. THUS, OUR BALANCED REACTIONS IS:
