Water (H
2O) is a polar inorganic compound that is at room temperature a tasteless and temperature a tasteless and odorless liquid, nearly colorless with a hint of blue. It is an important solvent for polar molecules in chemistry; it is known as the "universal solvent" for its ability to dissolve many substances.[8] It is commonly found in its solid, liquid, and gas forms in nature.

Water has hydrogen bonding and is strongly polar. This polarity allows it to separate ions in salts and strongly bond to other polar substances such as alcohols and acids, thus dissolving them. Its hydrogen bonding causes its many unique properties, such as having a solid form less dense than its liquid form, a relatively high boiling point of 100 °C for its molar mass, and a high heat capacity.
Water is amphoteric, meaning it is both an acid and a base—it produces H+ and OH− ions by self ionization. This regulates the concentrations of H+ and OH− ions in water.
Because water is a very good solvent, water is rarely pure and some of its properties vary from those of the pure substance. However, there are also many compounds that are essentially, if not completely, insoluble in water, such as fats, oils and other nonpolar substances.
