Abstract 1,1,3,3-Tetraethylurea (TEU), a solvent of relatively low dielectric constant, 14.4, was evaluated as a medium for conductance studies of a series of alkali metal salts and organic acids. Conductance data for KSCN, NaSCN, NaI, NaClO4, and NaBPh4 in TEU were analyzed by the Fuoss-Shedlovsky, Fouss-Onsager, and expanded Pitts equations. The behavior of these salts in TEU was compared with that of the same salt series in the previously studied tetramethylurea. Tetraethylurea also was used successfully as a solvent for conductometric titrations of several carboxylic acids and phenols.
