Electrolytes are solid and liquid substances predominantly with ionic conductivity. Electrolytes are substances that are subject in liquid solutions to electrolytic dissociation while interacting with the solvent. Electrolyte solutions are often also called electrolytes. Electric current in electrolytes is caused by the movement of ions and is accompanied by chemical reactions on metal electrodes. There are conductors with mixed conductivity in which an electric current is carried by both ions and electrons (for example, solutions of alkali metals in liquid NH3).
In some solid electrolytes electricity is carried by ions of only one sign (unipolar conduction).Electrolyte solutions are complex systems, which properties depend on nature of interactions between molecules of ion and solvent, as well as on nature of ions with solvent molecules. |
