Oxidation vs. Combustion: Know the Difference
By Dua Fatima & Shumaila Saeed || Published on March 8, 2024
Oxidation is the process of a substance losing electrons, often to oxygen, while combustion is a specific type of oxidation that involves burning in the presence of oxygen, producing heat and light.
Key Differences
Oxidation is a chemical process where a substance loses electrons, which can occur with or without oxygen. Combustion, on the other hand, is a specific type of oxidation reaction that happens rapidly, involving a fuel and oxygen, and typically produces heat and light.

In oxidation, the substance that loses electrons is said to be oxidized. This process does not necessarily involve fire or heat. Combustion is always exothermic, releasing energy in the form of heat and often light, like in a fire.

Oxidation reactions are part of a broader set of chemical processes and can happen slowly, such as when metal rusts. Combustion reactions are a subset of oxidation and occur quickly, like in the burning of wood or fossil fuels.

Oxidation can occur under a variety of conditions, not always requiring high temperatures. Combustion requires specific conditions to sustain the reaction, including the presence of a fuel, oxygen, and a source of heat.
