The solvent is a liquid (gas or solid) capable of dissolving a solid, liquid or gaseous solute (the solvent and solute can be solid, liquid or gas), and then becomes a solution. The most common solvent in everyday life is water. The organic solvent is an organic compound containing carbon atoms. Solvents generally possess relatively low boiling points and are readily volatile. Or can be removed by distillation, leaving a solute. Thus, the solvent may not chemically react with the solute. They must be inert. The solvent may extract soluble compounds from the mixture, the most common example being brewing coffee or tea with hot water. Solvents are generally clear, colorless liquids, most of which have a distinctive odor.
