Abstract
Apparent molar volumes (phi(v)) and apparent molar adiabatic compressi bilities (phi(K)) of four symmetrical tetraalkylammonium bromides have been determined in 1,2-dimethoxyethane from precise density and sound velocity measurements. Limiting apparent molar volumes and adiabatic compressibilities of the salts obtained from the concentration depende nce of phi(v) and phi(K) data are separated into ionic contributions. The data have been quantitatively interpreted in terms of solute-solve nt and solute-solute interactions. Strong electrostriction occurs arou nd bromide ions whereas the larger tetraalkylammonium ions which are s carcely solvated in 1,2-dimethoxyethane, cause a greater degree of dis order in the solvent structure.
