Abstract:

The theory of KH₂PO₄ developed by Yomosa and the present writer can be applied to the upper phase of NH₄H₂PO₄ without any alteration. All the experimental data can be represented by the formulas of this theory. It is shown that this theory has a more general character than it appears as based upon Slater's model of KH₂PO₄, and, when applied to Rochelle salt, it is equivalent to Mueller's interaction theory. Some discussions on the phase change in NH₄H₂PO₄ are given.
