Oxidation and Reduction

These flashcards cover key terms and concepts related to oxidation and reduction reactions, essential for understanding their processes and applications.

Oxidation

The loss of electrons or the gain of oxygen.

Reduction

The gain of electrons or the loss of oxygen.

Oxidizing Agent

A substance that gains electrons and is reduced, causing oxidation of another substance.

Reducing Agent

A substance that loses electrons and is oxidized, causing reduction of another substance.

Oxidation Number

A measure of the degree of oxidation of an atom in a substance, reflecting the transfer of electrons.

LEO says GER

An acronym to remember that Loss of Electrons is Oxidation, Gain of Electrons is Reduction.

Rust Formation

An oxidation–reduction reaction where iron reacts with oxygen to form rust (Fe2O3).

Electrochemical Cell

A device that generates electricity from oxidation and reduction reactions.

Half-reactions

Separate equations that represent the oxidation and reduction components of a redox reaction.

Photosynthesis

The process by which plants convert carbon dioxide and water into glucose and oxygen, involving oxidation and reduction.
