sentence: Solvents are usually clear and colorless liquids and many have a characteristic smell.
sentences_before: These are called 'organic solvents'. Solvents usually have a low boiling point and evaporate easily or can be removed by distillation, thereby leaving the dissolved substance behind. Solvents should therefore not react chemically with the dissolved compounds - they have to be inert. Solvents can also be used to extract soluble compounds from a mixture, the most common example is the brewing of coffee or tea with hot water.
sentences_after: The concentration of a solution is the amount of compound that is dissolved in a certain volume of solvent. The 'solubility' is the maximal amount of compound that is soluble in a certain volume of solvent at a specified temperature.
