On a simple method for measuring the affinity between a solvent and a soluted body

Abstract

Let us have a unit volume of a solution of body X in some solvent Y; add to the solution of another solvent Z, which dissolves solvent Y well, but practically does not dissolve body X, even if solvent Z is mixed a little with solvent Y. Then solvent Z will begin to pull solvent Y out of the solution and body X should precipitate in crystals.
