The volume changes on mixing aqueous solutions of guanidinium bromide with those of tetrabutyl- and tetramethylammonium bromide were measured with a vibration densimeter at 25 °C. The excess volume change of mixing was positive and large for the system of tetrabutylammonium bromide–guanidinium bromide–water. On the basis of the interaction parameters of Friedman's formalism, this result was interpreted in terms of an interaction between guanidinium cation and tetrabutylammonium cation through the change of water structure.
