- Physical Chemistry.
- a conducting medium in which the flow of current is accompanied by the movement of matter in the form of ions.
- any substance that dissociates into ions when dissolved in a suitable medium or melted and thus forms a conductor of electricity.
- any of certain inorganic compounds, mainly sodium, potassium, magnesium, calcium, chloride, and bicarbonate, that dissociate in biological fluids into ions capable of conducting electrical currents and constituting a major force in controlling fluid balance within the body.
- a solution or molten substance that conducts electricity
- a chemical compound that dissociates in solution into ions
- any of the ions themselves
