Precise vapor-pressure data for solns. of lithium hydroxide in water at 298.15-363.15 K were measured by a procedure and equipment known to yield data of high precision. The investigated range of LiOH soln. molality was from 0.07 to 4.77 mol·kg-1. The values of the osmotic coeff. have been calcd., taking into account the second virial coeff. in the equation for the water vapor pressure. Adjustable parameters of Pitzer's model with Archer's extension and of the mean spherical approxn. of a nonrandom two-liq. model were evaluated. The new exptl. data are compared to literature values, which exhibit a surprising scattering.
