Question

Explain the redox process with an example. 

Answer

Redox reaction is a reaction in which oxidation and reduction take place simultaneously.

For example: The formation of Magnesium oxide from Mg and O2 is a redox reaction.

2Mg + O2 = 2MgO

Here magnesium is oxidised by loss of two electrons per atom to form Mg2+ ion and oxygen gains two electrons per atom O2- ion.

2Mg – 4e → 2Mg2+ (Oxidation)

O2 + 4e → 2O2- (reduction)
