A solvent (from the Latin solv, "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution.A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid.Water is a solvent for polar molecules and the most common solvent used by living things; all the ions and proteins in a cell are dissolved in water within the cell. The overall behavior of a solvent is characterized by three terms: a non-polar (dispersive) term, a polar term and a hydrogen-bonding term.
