A vector quantity whose magnitude is dependent on the product of the charges and the distance
between them. The direction of the moment is from the positive to the negative pole.
Dispersion force
A weak intermolecular force that arises from interactions between temporary and/or induced
dipoles. Also called London force.
Dissociation
The separation of a single species into two separate species; this term is usually used in reference to
salts or weak acids or bases.
Dissolution
The process of dissolving a substance. The opposite of precipitation.
Dynamic equilibrium
A state of balance (no macroscopic change observable) that arises when opposing processes occur
at equal rates.
Electrochemical cell
A cell within which a redox reaction takes place, containing two electrodes between which there is
an electrical potential difference. See Electrolytic cell; Voltaic cell.
Electrode
An electrical conductor through which an electric current adjust enters or leaves a medium.
Electrolysis
The process in which an electric current is passed though a solution, resulting in chemical changes
that would not otherwise occur spontaneously.
