Arrhenius doctrine

Pronunciation: a-re'ne-us

Definition: the theory of electrolytic dissociation (1887) that became the basis of the modern understanding of electrolytes. In an electrically conductive solution (acid, base, or salt), free ions are present before electrolysis, and the proportion of molecules dissociated into ions can be calculated from measurements of electrical conductivity as well as of osmotic pressure.

Synonym(s): Arrhenius law
