No, acetone is an organic solvent and it will not dissolve salt (sodium chloride, NaCl). The principal type of solute-solvent interaction for an electrolyte dissolved in water is ion-dipole interactions. so to get anything to dissolve in it it has to be nonpolar. (a) KCl dissolved in water is an example of an electrolyte dissolved in water. NaCl dissolves in water but not in benzene because the water-ion interactions are stronger than benzene-ion interactions. so i would assume this would dissolve Benzene. Benzene is a nonpolar solvent, so the HCl remains as molecules in the solution. In CH3CH2OH you can expectlondon and dipole dipole forces and Hydrogen bonding as well, in NH3 has london dipole and hydrogen bonding. See below for the correct answer. Benzene has a heat of vaporization of 44.3 kJ/mol and a heat of fusion of 9.84 kJ/mol. In the presence of 18-crown-6, potassium permanganate dissolves in benzene to give purple benzene, a useful reagent for oxidizing alkenes in an aprotic environment.
