1. Key Ideas

The bleach under your sink works by ripping electrons from the molecules in stains and bacteria — oxidation doesn’t require oxygen at all, and understanding why changes everything about how you read a chemical equation.

3. Key Terms

OIL RIGIf this feels backwards, it is — commit OIL RIG and the oxidant/reductant definitions to memory as a pair.

redox reactionA reaction involving the transfer of electrons between chemical species.

reductantOxidised — these relationships feel counterintuitive and must be memorised precisely.

oxidantReduced; the reductant is oxidised — these relationships feel counterintuitive and must be memorised precisely.

oxidisedThe species that is oxidised (loses electrons) is called the reductant — it provides electrons to the other species.

Synthesis reactionA reaction where two or more reactants combine to form a single product.
