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) - φv0), of these solutions have been fitted to an equation of the form φv(P) - φv(0) = φv 0(P) - φv 0(0) + Sm1/2 where the relative infinite dilution partial molal volumes, φv 0(P) - φv 0(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.
