introduction to redox reaction
Redox is derived from the words reduction and oxidation. It is a process characterized by the increase and decrease of the oxidation number, the value assigned to an atom or ion to keep track of the electrons that are gained or lost.
Oxidation is the process in which a substance loses electrons/hydrogen or gains oxygen. It is characterized by the increase in the oxidation number of an atom. An oxidizing agent is a substance that causes another substance to lose electrons (oxidize). Rusting, combustion, and cellular respiration are examples of oxidation reactions.
Reduction is a process in which a substance gains electrons/hydrogen or loses oxygen. It is characterized by the decrease in the oxidation number. A reducing agent is a substance that causes another substance to lose electrons (reduce).
Mnemonics are used to finely understand the redox reactions: ELORA/ LEORA for “Electron Loss is Oxidation and that species is a Reducing Agent”; and GEROA for “Gain of Electrons is Reduction and that species is an Oxidizing Agent”.
