Abstract
Earlier experiments with 15 strong electrolytes have been extended to 38 and there continues to be a striking correspondence between the rate of variation of the partial molal ionic volume with concentration and the rate of variation of water structure as crudely indicated by the x‐ray diffraction pattern. The concentration in mole fraction of the solutions varied from 0.001 to 0.096 having a mean of 0.028. The influences of concentration on adiabatic compressibility and of solubility on the variation of water structure are mentioned. Qualitative explanation of the effect of the ions in solution may be obtained by assuming a direct effect on the breaking of H bonds and the indirect effect of altering the pure temperature expansion of the water.
