What is Oxidation?
Oxidation is a chemical reaction in which a substance loses electrons. This leads to an increase in the oxidation state of the substance.
Examples of Oxidation
1. Rusting of iron: When iron is exposed to oxygen and moisture, it undergoes oxidation, forming iron oxide (rust).
2. Tarnishing of silver: Silver objects can become tarnished when they react with sulfur compounds in the air, leading to the oxidation of the silver.
3. Burning of wood: When wood burns, it undergoes oxidation as it reacts with oxygen in the air, producing carbon dioxide and water vapor.
Oxidation in Everyday Life
Oxidation is a common process that occurs in many everyday situations. It is responsible for the browning of fruits and vegetables when they are cut, the formation of patina on copper surfaces, and the aging of wine.
Oxidation and Corrosion
Corrosion is a type of oxidation that specifically refers to the deterioration of metals due to chemical reactions with their environment. It often leads to the weakening and eventual breakdown of the metal.
Preventing Oxidation
Various methods can be used to prevent or slow down oxidation, such as applying a protective coating, using antioxidants, or controlling the environment to minimize exposure to oxygen and moisture.
