A STUDY OF ION-ION AND ION-SOLVENT INTERACTIONS.
Abstract
Previous analyses of the properties of aqueous-alcohol mixtures are now extended to aqueous mixtures containing an aprotic co-solvent, methyl cyanide. Three techniques have been employed. The first involves measurement of the sound absorption properties over the frequency range 1.5 to 230 Mc/s (using a pulse technique) and 200 to 1500 Kc/sec (using a reverberation technique). The second technique involves analysis of the effect of added methyl cyanide on the near infra-red absorption spectrum of deuterium oxide containing 6 m water. The third technique involves measurement of the ultraviolet absorption spectrum of iodide ion in the aqueous mixtures. It is generally accepted that dissolution of alcohols in water is dominated by entropy changes, but that dissolution of solvents such as methyl cyanide is enthalpy controlled. Some consequences of this are examined. (Author)
