oxidation
Let an agent explain oxidation in its modern electron-transfer sense and its historical oxygen sense, identify oxidation in a given reaction by oxidation states, relay examples from chemistry, biology and industry, and separate it from related processes such as corrosion and combustion as wholes.

Purpose and description
Let an agent explain oxidation in its modern electron-transfer sense and its historical oxygen sense, identify oxidation in a given reaction by oxidation states, relay examples from chemistry, biology and industry, and separate it from related processes such as corrosion and combustion as wholes.
A chemical process in which a substance loses electrons, or in the older and everyday sense combines with oxygen, always paired with a reduction of another substance in a redox reaction; oxidation drives combustion, corrosion, respiration, metabolism, browning of food and many industrial syntheses, and is measured by changes in oxidation state.
What it is for: Not for anything in itself; a class of chemical change.
It can be explain the definition and its history; assign oxidation states and identify what is oxidised; give examples across chemistry, biology and industry; distinguish oxidation from reduction, combustion and corrosion.
Distinguishing features
Electron loss defines it
Half of every redox reaction
Oxygen need not be involved
Tracked by oxidation states
What it looks like
Not visible in itself; seen in rust, browning, flames and colour changes.
How it is recognised
Loss of electrons or increase in oxidation state
Always paired with a reduction
Combustion and corrosion are processes that involve oxidation

What the second pass must settle

- How should oxidation state conventions be linked?
- The registry entry has merged aliases for specific reactions such as caramelisation; should they be split off?
