A Solvent is a liquid that can dissolve a solid, liquid, or gaseous solute and then become a solution. The most common solvent in everyday life is water. The so-called organic solvent is the solvent of organic compounds containing carbon atoms. Solvents usually have relatively low boiling points and are easily volatile. Or it can be removed by distillation, leaving behind the dissolved substance. Therefore, the solvent cannot react chemically to the solute. They must be low active. Solvents can extract soluble compounds from mixtures, the most common example being hot water for brewing coffee or tea. Solvents are usually clear, colorless liquids, and most of them have a distinctive odor
