Abstract
Aqueous equilibrium constants for reactions involving fluoro-, hydroxy -, and amido-substituted phosphoric acids with HF have been determined at several temperatures. From these values, the formation thermodynam ics have been calculated for monofluorophosphoric acid, difluorophosph oric acid, and amidofluorophosphoric acid. The stability of the OH-sub stituted compounds is distinctly greater than both the F- and the NH2 substituted compounds.
