EXAMPLE FOR OXIDATION AND REDOX REACTION

Oxidation reaction involves addition of oxygen to a substance or removal of hydrogen from a substance .

Example 1 : 2CuO  +O₂  __________> 2CuO 

In the above reaction copper gains oxygen ,thus oxidation of copper to copper oxide takes place .

Example 2: 2KI  +H₂O₂  __________> 2KOH  +I₂

Potassium iodide loses electropositive radical potassium and therefore oxidised to iodine. This is an oxidation reaction which involves removal of an electropositive element .

Redox reactions are reaction which involves oxidation of one substance and reduction of the other .It involves loss or gain of electrons where oxidation and reduction occur simultaneously .

Example :
