During a redox reaction : (C) Some atoms gain electrons and some lose electrons.

Explanation:

Redox reaction

A reaction in which both oxidation and reduction occur simultaneously .

Before studying about redox reaction we should know about oxidation and reduction .

Oxidation and Reduction

In terms of Classical concept

Oxidation: Oxidation is defined as “addition of oxygen or any electronegative element and removal of hydrogen or any electropositive element”.

Reduction: Reduction is defined as” addition of hydrogen or any electropositive element and removal of oxygen or any electronegative element”.

Please note: the substance that undergo oxidation itself and reduce other is called reducing agent whereas the substance that undergo reduction itself and oxidize other is called oxidizing agent.

For example :

CuO+ H₂--> Cu + H₂O

In reaction, Cu is undergoing reduction and oxidizing hydrogen. Therefore, Cu is oxidizing agent and H is reducing agent.

“As in this reaction both oxidation and reduction occur simultaneously, therefore reaction is called redox reaction.”

In terms of Electron transfer concept

Oxidation: is defined as loss of electrons that is :

Reduction: is defined as gain of electrons that is:

Example of Redox reaction in terms of electron transfer:

Mg + Cl₂--> MgCl₂

In this Magnesium is loosing electrons, that is undergoing oxidation and chlorine is gaining electrons therefore, it is undergoing reduction. Mg is Reducing agent in it and Cl is Oxidizing agent in it.

Hence , the redox reaction occurs .
