Redox reactions are chemical reactions in which oxidation and reduction happen together. Oxidation means loss of electrons or increase in oxidation number, while reduction means gain of electrons or decrease in oxidation number. These reactions are important in burning, rusting, metal extraction, ba
Key Concepts
Oxidation is the process in
Oxidation is the process in which a substance adds oxygen or removes hydrogen in the classical view. In the electronic view, it is loss of electrons.
Reduction is the process in
Reduction is the process in which a substance adds hydrogen or removes oxygen in the classical view. In the electronic view, it is gain of electrons.
An oxidising agent provides oxygen
An oxidising agent provides oxygen or removes hydrogen in the classical view. In the electronic view, it gains electrons and gets reduced. In the oxid

A redox reaction is a reaction
A redox reaction is a reaction in which electrons are transferred from one reactant to another. It is also a reaction in which species undergo a chang
