250gm mass of VO₂Cl₂⁻ 2 or VOCl₃ can form from 12.5 g of V₂O₅ and the appropriate concentration of acid.
Ionic liquids are also employed as auxiliaries and catalysts in chemical synthesis. They are used in analytical equipment. They make up electrolytes in lithium-ion batteries, supercapacitors, and metal plating baths. They can be found as lubricants and coolants.
ions
Ionic liquids (ILs) are normally defined as compounds completely composed of ions with melting point below 100 °C. The first IL (ethylammonium nitrate) was reported by Paul Walden in 1914, who at that time never realized that ILs would become a major scientific area after almost one century.
