A solvent is a liquid (gas, or solid) that dissolves a solid, liquid, or gaseous solute (a solvent, a solute can be a solid, a liquid, a gas), and then a solution. The most common solvents in everyday life are water. The so-called organic solvents are organic compounds containing carbon atoms. Solvents usually have a lower boiling point and are easily volatile. Or it can be removed by distillation, leaving the soluble. Therefore, solvents can not produce chemical reactions to the solute. They must be inert. Solvents can be extracted from a mixture of soluble compounds, the most common example being the use of hot water to brew coffee or tea. Solvents are usually transparent, colorless liquids, and most of them have unique odors.
