Understand the definition of oxidation and reduction in a redox reaction: oxidation involves the loss of electrons, while reduction involves the gain of electrons.
Identify the substance that loses electrons as the one undergoing oxidation.
Recall that the substance that loses electrons is called the reducing agent because it donates electrons to another substance.
Note that the oxidizing agent is the substance that gains electrons (is reduced) by accepting electrons from the reducing agent.
Recognize that terms like catalyst and product do not specifically describe electron transfer roles in redox reactions.
