Ionic liquids are a class of liquid salts that are composed entirely of ions and have very low melting points, typically below 100°C. They have unique physical and chemical properties, such as high thermal stability, low volatility, and tunable solubility. Due to their versatility, ionic liquids have been studied for a wide range of applications, including as solvents for organic reactions, electrolytes in batteries, and catalysts in chemical processes. Research in the field of ionic liquids aims to further understand their properties and explore their potential in various industries.
