Abstract
The densities of aqueous solutions of NaCl, KCl, MgCl2, Na2SO4, and MgSO4 have been measured with a high pressure magnetic float densimeter from 0 to 1000 bars, 0.01 to 1.0 m ionic strength, and at 0, 25, and 50 °C. The relative apparent molal volumes, ϕv(P) ‒ ϕv(0), of these solutions have been fitted to an equation of the form ϕv(P) ‒ ϕv(0) = ϕv°(P) ‒ ϕv°(0) + Sm½ where the relative infinite dilution partial molal volumes, ϕv°(P) ‒ ϕv°(0), and the slopes S are functions of applied pressure and temperature. The pressure, temperature, and concentration dependence of the apparent molal volumes are briefly discussed.
