Method for determining composition of a solid phase in a ternary system at constant temperature and pressure by analysis of the total mixture of solid and liquid in equilibrium.
Notes:
  1. The method relies on the fact that the wet residue lies on the tie-line connecting the solid phase and the saturated liquid phase. Equally well, the initial mixture of solid and liquid used in the solubility experiment can be used, when it is referred to as the "initial complex" method. In either case, two or more tie-lines intersect at the composition of the solid phase.
  2. The method is generally more reliable than isolation and analysis of the solid phase, especially when the solid phase is a hydrate.
