Redox Reactions Flashcards

Front

Anode

Back

The electrode where oxidation occurs in an electrochemical cell.

Front

Cathode

Back

The electrode where reduction occurs in an electrochemical cell.

Front

Electrochemical cell

Back

A device that generates electrical energy from chemical reactions or facilitates chemical reactions through the introduction of electrical energy.

Front

Electrolytic cell

Back

A type of electrochemical cell that uses electrical energy to drive a non-spontaneous flow of electrons

Front

Half reaction

Back

The part of the reaction involving oxidation or reduction alone.

Front

Oxidation

Back

The process of losing electrons during a chemical reaction.

Front

Oxidation-Reduction Reaction

Back

A chemical reaction where the oxidation state of atoms are changed, involving the transfer of electrons.

Front

Oxidation number

Back

The apparent charge of an atom

Front

Redox

Back

A type of chemical reaction in which both oxidation and reduction take place simultaneously (transfer of electrons).

Front

Reduction

Back

The process of gaining electrons during a chemical reaction.
