A redox reaction is a chemical reaction in which there is a transfer of electrons between two substances. This transfer of electrons causes a change in the oxidation states of the substances involved.
Redox reactions can be identified by the change in oxidation states of the substances involved. The substance that loses electrons is oxidized and the substance that gains electrons is reduced.
Redox reactions play a crucial role in many everyday processes such as respiration, photosynthesis, and corrosion. They are also used in batteries, fuel cells, and other important industrial processes.
An example of a redox reaction is the reaction between iron and oxygen to form rust. In this reaction, iron loses electrons to oxygen, causing it to oxidize and form iron oxide (rust).
Redox reactions are balanced by making sure that the number of electrons lost by the oxidized substance is equal to the number of electrons gained by the reduced substance. This is done by adding appropriate coefficients to the reactants and products in the chemical equation.
