Oxidation and Reduction
Redox is a short form for reduction and oxidation reactions. The two reactions are opposing and complementary and they occur simultaneously. Redox has the following definitions
1. Definition of Oxidation Reactions with Examples
(a) In Terms of Addition of Oxygen:
Oxidation is the addition of oxygen or removal of hydrogen from a substance. Any reaction where there is addition of oxygen to a reactant is regarded as Oxidation.
Some examples are:
(i) 2Mg(s) + O2(g) → 2MgO(s) oxidation of magnesium
(ii) C(s) + 2ZnO(s) → CO2 (g) + 2Zn(s)
In this reaction, oxygen (O) was added to carbon (C) to form Carbon (iv) oxide (CO2).
