An<unk>  is a<unk>  that contains essentially only ions.  Some<unk> s, such as ethylammonium nitrate are in a dynamic equilibrium where at any time more than 99.99% of the<unk>  is made up of<unk>  rather than molecular species. In the broad sense, the term includes all molten salts, for instance, sodium chloride at temperatures higher than 800 °C. Today, however, the term<unk> " is commonly used for salts whose melting point is relatively low (below 100 °C). In particular, the salts that are<unk>  at room temperature are called room-temperature<unk> s, or RTILs. There also exist mixtures of substances which have low melting points, called Deep eutectic solvent, or DES, that have many similarities with<unk> s.
