The transport numbers of the chloride ion in the pure molten alkaline earth chlorides have been determined. A modified Stokes' law was applied to the motion of the individual ions. Application of the assumptions made in invoking this law gave a qualitative estimate as to the degree of association in MgCl 2, CaCl2, SrCl2, BaCl2, ZnCl2, and PbCl2 • Several trends were observed which were consistent with the chemical properties of the salts studied.
