Abstract

The apparent molar volumes of four symmetrical tetralkylammonium perchlorates (Me(4)NClO(4), Et(4)NClO(4), Pr4NClO4 and Bu(4)NClO(4)) have been determined in 2-methoxyethanol (ME) + water mixtures containing 20, 40, 60 and 80 mass% of 2-methoxyethanol at 25 degrees. The apparent molar volumes are extrapolated to zero concentration to obtain the limiting values at infinite dilution. Ionic limiting partial molar volumes have been estimated using the extrapolation method. Ion ion interactions are found to be very weak but increase with increasing amount of 5-methoxyethanol in the solvent mixtures. The results have been explained on the basis of the electrostriction effect of the perchlorate ion and the hydrophobic and size effects of the tetraalkylammonium ions.
