The Conductance Of Some Polyvalent Electrolytes, Jack Lee Worthington

Masters Theses

A new compound, 1,3,5-triphenylbenzene-4' ,4",4"'-trisulfonic acid, was synthesized by treating triphenylbenzene in 1,2-dichloroethane with chlorosulfonic acid. The reaction appears to be quantitative. Conductance measurements were then made on the sodium, potassium, and lanthanum salts of this new acid and of 1,3,5-benzenetrisulfonic acid.

The choice of these acids was based on two factors: 1) the desire to prepare a 3-3 symmetrical unassociated electrolyte which would allow the determination of a more reliable equivalent ionic conductance value for La³⁺ and 2) an interest in using the Murphy-Cohen equation to determine solute parameters such as association constants if association is present.

Computer Investigation Of The Variation Of Conductivity With Concentration, Larry Macpeers Shadwick

Masters Theses

Computer programs were developed tor the conductance equations of R. M. Fuoss and L. Onsager as well as for the conductance equations of T. J. Murphy and E. G. D. Cohen. These programs were used to calculate values from selected conductance measurements. The resulting values were compared with values produced by other computer programs using the equations of Fuoss and Onsager as well as the equations of E. Pitts. The comparisons demonstrated the equations of Murphy and Cohen to be the equal of or superior to the other equations for the majority of cases. The equations of Pitta were superior …
