  • <em><u>Oxidation</u></em> may also be referred to as<em><u> increase in the oxidation state of an atom while reduction is the decrease of oxidation state </u></em>of an atom.
  • The presence of hydrogen gas as a reactant is a best indicator of an oxidation-reduction reaction. This is because in hydrogen gas hydrogen has a zero oxidation number which may increase to show oxidation or may decrease to show reduction after the reaction.
