Oxidation
ˌɒksɪˈdeɪʃən
Definitions
The chemical reaction that involves the loss of electrons by a molecule, atom, or ion. It often (but not always) involves the combination of a substance with oxygen.
ˌɒksɪˈdeɪʃən
The process of combining with oxygen or losing electrons.
The oxidation of metals can lead to corrosion.
💡 Simply: Imagine a shiny apple left out; it turns brown because it's being 'oxidized' – its surface is reacting with air, changing its color. Oxidation is a general term in chemistry where a substance 'loses' electrons.
👶 For kids: When something gets rusty or turns brown because it's been in the air, that's oxidation!
More Examples
Researchers are studying the oxidation process in fuel cells.
Antioxidants help to slow down the oxidation of cells in the body.
The fruit's brown color is the result of oxidation.
How It's Used
"The oxidation of iron creates rust."
"Cellular respiration involves the oxidation of glucose."
"The oxidation of pollutants in wastewater treatment is a common process."
From French oxydation, from oxyder ('to oxidize'), from oxygène ('oxygen'). The process was initially understood in terms of oxygen combining with a substance. Later, it was broadened to include reactions involving the loss of electrons.
The term 'oxidation' gained widespread usage in the 19th century with the development of modern chemistry. Initially limited to oxygen combination reactions, its meaning has broadened over time.
Memory tip
Think of oxygen as the oxidizing agent; it steals electrons!
