An oxidation-reduction (redox) reaction is a type of chemical reaction that involves the transfer of electrons between substances.

Oxidation: This is the process where a substance loses electrons. For example, when iron (Fe) rusts, it loses electrons to oxygen, leading to the formation of iron oxide (Fe₂O₃).
Reduction: This is the opposite process, where a substance gains electrons. For instance, in the reaction of hydrogen (H₂) with oxygen (O₂) to form water (H₂O), oxygen gains electrons.

Energy Production: Redox reactions are fundamental in energy production, such as in batteries and biological processes like respiration.
Chemical Reactions: They play a crucial role in various chemical reactions, including combustion and corrosion.

In summary, redox reactions are vital for many natural and industrial processes, highlighting the importance of electron transfer in chemistry.
