  "definition": "1. A chemical reaction consisting of two half-reactions; an oxidation reaction in which a substance loses or donates electrons and a reduction reaction in which a substance gains or accepts electrons. Redox reactions are always coupled because free electrons cannot exist in solution and electrons must be conserved.\n\n2. A chemical reaction involving transfer or electrons from one element to another.\n\n3. Chemical reaction consisting of an oxidation reaction in which a substance loses or donates electrons, and a reduction reaction in which a substance gains or accepts electrons. Redox reactions are always coupled because free electrons cannot exist in solution and electrons must be conserved.",
