Hydrochloric acid (HCl) dissociate on positive ions or cations of hydogen (H⁺) and negative ions or anions of chlorine (Cl⁻). When there is free cations and ions, water solution can conduct electricity. Chloroform do not dissociate on ions in water, because that is not polar molecule, so chloroform is in molecular form in solution.
