Therefore hexane is not soluble in water. Polar solvents The electron affinities generally decrease (meaning less heat is emitted), but the fluorine value deviates from this trend. WebTo test the solubility of hexane, cyclohexene and toluene in water, add 1 mL (no more) of each hydrocarbon to three clean test tubes containing about 5 mL water. In one equation, use an, A:a. Because it is made of non-polar molecules and water is made of polar molecules, they do not dissolve together. For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. H2O And as Cl gains an electron, the forces between the electrons increases, causing them to expand and making the ion bigger. b. NH4 or CH4 Start your trial now! The solubility of chloroform (CHCl3) at the same temperature is 10.1 g/L. Direct link to Yorba's post Just curious at 3:59 Is O, Posted 11 years ago. Thus neither hexane nor iodine dissolves in water.
