Generally an enthalpy‐concentration diagram for a system is prepared for fixed pressure, and to be complete it should include data on the solid, liquid, and vapor phases. Such charts are useful for calculations involving heat balances with accompanying concentration changes. This article outlines the steps in the preparation of a diagram and includes the diagrams for aqueous solutions of hydrazine, sodium carbonate, and glycerine.
