Reduction results in a decrease in the oxidation state of the substance being reduced.
In redox reactions, reduction is always accompanied by oxidation of another species.
Common examples include the reduction of metals from their ores and the hydrogenation of organic compounds.
The substance that gains electrons (gets reduced) is called the oxidizing agent.
Redox reactions are essential in processes like respiration, photosynthesis, and corrosion.
