Chemical and Physical Properties in Aqueous Solutions

Small-angle X-ray scattering results are presented for a number of liquid alloys of the Na-K system. The analysis in terms of the concentration-fluctuation structure factor SCC(0) proves to be rather cumbersome and is considered in some detail. There are distinct indications that concentration fluctuations occur in the liquid. Comparisons with the related Na-Cs system are made throughout. Some simple theoretical models are considered and comparison with thermodynamic data has been made.
