Oxidation is a fundamental chemical process involving the loss of electrons by an atom or a group of atoms.
Defining Oxidation
According to the provided reference, oxidation can be defined in two primary ways:
- Electron Loss: Oxidation is a process that occurs when atoms or groups of atoms lose electrons. This is the most fundamental definition.
- Oxygen Gain or Hydrogen Loss: Another way to define oxidation is when a chemical species gains oxygen or loses hydrogen.
Understanding Oxidation with Examples
To further understand oxidation, consider these examples:
-
Rusting of Iron: Iron reacts with oxygen in the presence of water to form iron oxide (rust). Iron atoms lose electrons (oxidation) to oxygen atoms, which gain electrons (reduction).
-
Burning of Fuel: When fuels like wood or natural gas burn, they react with oxygen. Carbon atoms in the fuel lose electrons (oxidation) to oxygen atoms.
Oxidation vs. Reduction
Oxidation always occurs alongside reduction. When one substance loses electrons (oxidation), another substance gains those electrons (reduction). This is known as a redox (reduction-oxidation) reaction.
Summary Table: Oxidation
| Feature | Description |
|---|---|
| Definition 1 | Loss of electrons by an atom or group of atoms. |
| Definition 2 | Gain of oxygen or loss of hydrogen by a chemical species. |
| Process Type | Chemical process |
| Accompanying Event | Reduction (gain of electrons) – forming a redox reaction. |
