ABSTRACT

Density, ultrasonic velocity, electrical conductivity, viscosity, and Raman spectra of methanolic Mg(ClO4)2, Mg(NO3)2, and Mg(OAc)2 solutions were measured as functions of concentration (dilute to saturation) and temperature (273.15 e T/K e 313.15). The isentropic compressibility, electrical conductivity, and Raman spectral data reveal the following order of anion-solvent interactions and mobility in methanol: OAc- less than NO3 - less than ClO4 -. Anionic effect on the isentropic compressibility and conductivity roughly appear to follow Hofmeister series. Transport properties and Raman spectra also indicate a moderate solvent-shared ion pairing in concentrated Mg(NO3)2 solutions.
