Redox Reactions and Oxidation Numbers

Flashcards covering key terminology and definitions related to redox reactions and oxidation numbers.

Oxidation

The loss of electrons by a species, resulting in an increase in its oxidation number.

Reduction

The gain of electrons by a species, resulting in a decrease in its oxidation number.

Oxidizing Agent

The substance that accepts electrons during a reduction reaction and undergoes a decrease in oxidation number.

Reducing Agent

The substance that donates electrons during a reduction reaction and undergoes an increase in oxidation number.

Oxidation Number (O.N)

A number that represents the total number of electrons that an atom either gains or loses in a chemical reaction.

Redox Reaction

A chemical reaction that involves the transfer of electrons between two species.

Combination Reaction

A type of redox reaction where two or more substances combine to form a single product.

Decomposition Reaction

A type of redox reaction where a single compound breaks down into two or more simpler substances.

Single Replacement Reaction

A type of redox reaction in which one element replaces another element in a compound.

Combustion Reaction

A type of redox reaction that typically involves a substance reacting with oxygen to produce energy (heat and light).
