The component of a slution present in the greatest amount. It is component that dissolves a solute.
A solvent (from the Latin solvō, "I loosen, untie, I solve") is a liquid, solid, or gas that dissolves another solid, liquid, or gaseous solute, resulting in a solution that is soluble in a certain volume of solvent at a specified temperature. Common uses for organic solvents are in dry cleaning (e.g., tetrachloroethylene), as a paint thinner (e.g., toluene, turpentine), as nail polish removers and glue solvents (acetone, methyl acetate, ethyl acetate), in spot removers (e.g., hexane, petrol ether), in detergents (citrus terpenes), in perfumes (ethanol), and nail polish, (part of how it stays on nails) and in chemical synthesis. The use of inorganic solvents (other than water) is typically limited to research chemistry and some technological processes.
