Oxidation

The loss of electrons during a reaction.

Reduction

The gain of electrons during a reaction.

Redox Reaction

A reaction that involves both oxidation and reduction.

Activity Series

A list of metals ranked by how easily they are oxidized.

Electronegativity

An atom’s ability to attract electrons in a bond.

Half-Reactions

Equations that show either oxidation or reduction alone.

Electrochemical Cell

A device that converts chemical energy to electrical energy (or vice versa).

Voltaic (Galvanic) Cell

A cell that produces electricity from a spontaneous redox reaction.

Electrolyte

A solution that conducts electricity by allowing ion flow.

Salt Bridge

A tube with ions that connects two half-cells and keeps charge balanced.

Porous Disk

A barrier that lets ions pass but keeps solutions separate.

Anode

The electrode where oxidation occurs.

Cathode

The electrode where reduction occurs.

Electrical Potential

The ability of a system to do work by moving electrons.

Standard Cell Potential (E°cell)

The voltage of a cell under standard conditions (1M, 1 atm, 25°C).

Reduction Potential

A measure of how easily a substance gains electrons.
