The concentration of the solution depends on the amount of matter dissolved in the solvent, and the solubility is the maximum amount of matter that the solvent can dissolve at a given temperature. Organic solvents are mainly used for dry cleaning (e.g., four vinyl chloride) for coating thinner (e.g. toluene, turpentine), for washing nail water or removing glue (e.g. acetone, methyl acetate, ethyl acetate), derusting (e.g. hexane), as detergent (lemon extract), used for perfume (alcohol) and for chemical synthesis (chemical synthesis).
Solvents and solutes can be broadly divided into polar radicals (hydrophilic) and nonpolar (hydrophobic). Polarity can be learned by measuring the dielectric constant or dipole distance of a substance.
