There are several reactions that can achieve the removal of . electrons from the drug. 3.Reducing agent. In chemistry, a reducing agent (also known as a reductant, reducer, or electron donor) is a chemical species that "donates" an electron to an electron recipient (called the oxidizing agent, oxidant, oxidizer, or electron acceptor ). Examples of substances that are common reducing agents include the alkali metals, formic acid ...Rusting of iron: In these cases, chemists say that the carbon and the iron metal have been oxidized to carbon dioxide and rust, respectively. Loss of hydrogen In other reactions, oxidation can best be seen as the loss of hydrogen. Methyl alcohol (wood alcohol) can be oxidized to formaldehyde:
