Chemistry

Corrosion

संक्षारण

In this Class 12 Chemistry topic from Chapter 02: Electrochemistry, students learn how metals gradually deteriorate through chemical or electrochemical reactions with their surroundings. The topic explains rusting of iron, the formation of anodic and cathodic regions, the role of moisture and oxygen, and the movement of electrons and ions during corrosion. It also introduces practical methods of prevention, including protective coatings, galvanisation, alloying, and cathodic protection, linking electrochemical principles with everyday examples and industrial applications.
