WGU Balance Redox
WGU (tg) Steps to balance Redox reactions
Question | Answer |
---|---|
Step 1 | Write half reactions (oxidation / reduction.) |
Step 2a | For each Half Reaction: Balance all elements, then hydrogen and oxygen last. |
Step 2b | Balance Oxygen using H2O. |
Step 2c | Balance Hydrogen using H+. |
Step 2d | Balance the electrons lost (oxidation) or gained (reduction). |
Step 3 | Multiply one or both half reactions by an integer so the electrons are equal. |
Step 4a | Combine the half reactions. |
Step 4b | Cancel out the identical species (i.e. electrons). |
Step 5 | Check that the elements and charges are balanced. |
