Ames National Laboratory is a government-owned, contractor-operated national laboratory of the U.S. Department of Energy (DOE), operated by and located on the campus of Iowa State University in Ames, Iowa.

For more than 70 years, the Ames National Laboratory has successfully partnered with Iowa State University, and is unique among the 17 DOE laboratories in that it is physically located on the campus of a major research university. Many of the scientists and administrators at the Laboratory also hold faculty positions at the University and the Laboratory has access to both undergraduate and graduate student talent.

Abstract

The conductances, transference numbers, and activity coefficients of aqueous solutions of the chlorides of lanthanum, cerium, praseodymium, and neodymium have been determined for concentrations up to 0.1 normal . The transference numbers were determined by the moving-boundary method as developed by Longsworth and MacInnes; the activity coefficients were measured by using concentration cells with transference; and the conductances were obtained with a conventional apparatus of the type recommended by Jones and Josephs. The accuracy of all measurements was within 0.1 per cent.
