Abstract : The electrical conductivities of 0.10M aqueous solutions of the salts R4N(+)A(-) where R is CH3, C2H5, C3H7, n-C4H9, and n-C5H11 and A(-) is Cl(-), Br(-), and I(-) were measured at 4C and 25C over the pressure range 1 atm to 4,000 kg/sq cm. The results of these measurements support the viewpoints that (1) the hydrophobic hydration atmospheres of these ions are fundamentally different from the coulombic hydration envelopes surrounding 'normal' ions such as the alkali metal cations, in particular being much more stable with respect to hydrostatic pressure, and (2) cation-cation interactions are important in solutions of the larger ions in this series.
