... POLAR SOLVENT such as WATER or acid will dissolve an IONIC SOLUTE such as salt. Gasoline, benzene or carbon tetrachloride (dry cleaning solvent) are NON-POLAR SOLVENTS and they will best dissolve non-polar solutes such as fats, oils, paints. Water does not dissolve fats and oils very well. (Use of a ...
