Consider a ternary system comprising solute species 1 and a mixed solvent (species 2 and 3). Assume that:

Show that Henry’s constant H₁ for species 1 in the mixed solvent is related to Henry’s constants H_1,2 and H_1,3 for species 1 in the pure solvents by:

Here x′₂ and x′₃ are solute-free mole fractions:
