Balancing Redox Equations in Acid |
Step 1: | Separate in half reactions. |
Step 2: | In each half reaction, balance all elements except O & H. |
Step 3: | Balance O by adding H2O. |
Step 4: | Balance H by adding H+. |
Step 5: | Balance charges by adding e-. |
Step 6: | Multiply all coefficients in 1 or both half reactions by an integer to get the number of e- in the two half reactions equal. |
Step 7: | Add the 2 half reactions together & cancel out any species that appear on both sides of net reaction. |
Step 8: | Check that charges and atoms are balanced. |
