WHAT IS REDUCTION?
- Reduction is a chemical reaction that involves the gaining of electrons by one of the atoms involved in the reaction between two chemicals.
- The term refers to the element that accepts electrons, as the oxidation state of the element that gains electrons is lowered.
WHAT IS OXIDATION?
- An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
- Hydrogen generally has an oxidation state of +1 in compounds.
- Oxygen generally has an oxidation state of -2 in compounds.
