It has been shown thatV1(T, p, x1) =V10(T, p- π1) and thatV2(T, p, x2) =V20(T, p- π2), where π1is the osmotic pressure of the solvent in a binary solution and π2is the osmotic pressure of the solution solute. An increase in pressure applied to the solution, the pure solvent and pure solute fromptop+ Δpcompresses the solution solvent and pure solvent by equal fractions
