Description
Summary:A conductance method has been used for thermal diffusion measurements on 44 aqueous organic and inorganic electrolytes at 25 C, mostly at a concentration of 0.01m. By suitable design of apparatus, measurements at considerably higher concentrations were possible. Departures from predicted behaviour are found to be explicable in terms of inherent systematic errors. Results are quoted as Soret coefficients and heats of transport. A qualitative interpretation of the results is given in the light of current ideas of ion-solvent interactions. (Author)
