Paper No. 110. 1 The term ionic constituent refers to the ion-forming portion of an electrolyte, without specification of the extent of dissociation, association, solvation, etc. See, e.g., reference (4), p. 60. Thus the ionic constituents in an aqueous solution of CdR are Cd! + and I-, regardless of the fact that, the actual species in solution may include hydrated cadmium ions, anionic complexes such as Cdl4!_, etc. Measurements of macroscopic properties yield information only on the components (Cdl-j and water) or the ionic constituents. Unusual values of these properties may suggest the microscopic nature of the species (e.g., ions). More detailed information on the nature of the species requires measurements sensitive to the species properties and distribution (e.g., spectra).Alternative methods of conductance measurement are pointed out, as are some aspects pertinent to the measurement of dielectric constant. The extent of coverage can easily be modified to suit the level of the course and the time available.Phenomenology: Ohm's Law Applied to Electrolytes rent occurs whether the system be liquid, solid, or gaseous, single component or multicomponent.
