Preferred Label : reduced species;
IUPAC definition : A term used to characterize the degree of reduction (or oxidation) in atoms, molecules
and ions. An atom in a molecule or an ion which has a low oxidation state. An element
or atom in a compound can be reduced by the reaction of an element or compound with
hydrogen, while it can be oxidized by reaction with oxygen. A reduced species can
be formed also through the gain of electrons (either at the negative electrode in
a cell or through transfer from another atom, ion or group of atoms in a chemical
reaction). For example, the carbon atom in CH sub 4 /sub and other hydrocarbons is
in a reduced state, while the carbon in CO sub 2 /sub is in an oxidized state. Similarly
the sulfur atom in H sub 2 /sub S is in a reduced state while that in sulfuric acid
(H sub 2 /sub SO sub 4 /sub ) is in an oxidized state.;
