Study Notes

Redox Reactions

A redox reaction is a chemical reaction where electrons are transferred between reactants.
In a redox reaction, the substance that gains electrons is called the oxidizing agent.
A common example of a redox reaction is combustion, where a fuel reacts with oxygen to produce heat and light.
In a redox reaction, the oxidation state of the reducing agent decreases because it loses electrons.
A false statement about redox reactions is that they always involve oxygen. Redox reactions can take place without oxygen, for example, in the rusting of iron.
