Adiabatic compressibilities of aqueous solutions of twenty-seven strong electrolytes were determined by measuring the velocities of a supersonic wave of approximately 106 cycles. When the values of the partial molal volumes of the solute, water, were computed, there was found a striking correlation of these values with the adiabatic compressibilities. An exact correlation cannot be expected both because of the empirical nature of the formulas used and also because there is no reason to suppose that the altered structure of the water is of the same kind in every electrolyte. The results, however, are strongly indicative of the view that ions alter the structure of the solute, the water becoming more dense with ionic concentration.
