[ ih-lek-truh-lahyt ]
/ ɪˈlɛk trəˌlaɪt /


Physical Chemistry.
  1. Also called electrolytic conductor. a conducting medium in which the flow of current is accompanied by the movement of matter in the form of ions.
  2. any substance that dissociates into ions when dissolved in a suitable medium or melted and thus forms a conductor of electricity.
Physiology. 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.

Medical definitions for nonelectrolyte (1 of 2)

[ nŏn′ĭ-lĕktrə-līt′ ]


A substance whose molecules in solution do not dissociate to ions and thus do not conduct an electric current.

Medical definitions for nonelectrolyte (2 of 2)

[ ĭ-lĕktrə-līt′ ]


A chemical compound that ionizes when dissolved or molten to produce an electrically conductive medium.
Any of various ions, such as sodium or chloride, required by cells to regulate the electric charge and flow of water molecules across the cell membrane.

Scientific definitions for nonelectrolyte

[ ĭ-lĕktrə-līt′ ]

A melted or dissolved compound that has broken apart into ions (anions and cations). Applying an electric field across an electrolyte causes the anions and cations to move in opposite directions, thereby conducting electrical current while gradually separating the ions. See also electrodialysis electrolysis.
Any of these ions found in body fluids. Electrolytes are needed by cells to regulate the flow of water molecules across cell membranes.

Cultural definitions for nonelectrolyte

[ (i-lek-truh-leyet) ]

A substance that can serve as a conductor for an electric current (see also current) when it is dissolved in a solution. Electrolytes are found in the blood and tissue fluids of the body.
