The Standard Chemical-Thermodynamic Properties of Phosphorus and Some of its Key Compounds and Aqueous Species: An Evaluation of Differences between the Previous Recommendations of NBS/NIST and CODATA

Abstract

The aqueous chemistry of phosphorus is dominated by P(V), which under typical environmental conditions (and depending on pH and concentration) can be present as the orthophosphate ions

Efficient Electrosynthesis of White Phosphorus from Molten Condensed Phosphate Salts

“…For the melts with the lowest anhydride population, the Tafel plots recoalesce at a −1.5 V overpotential. In line with literature reports and thermochemical reference data, we impute this high overpotential region to the reduction of orthophosphate (23,24,(40)(41)(42)(43)(44)(45)(46). Thus, we attribute this transition in the Tafel behavior to the local consumption of anhydrides near the electrode surface, a phenomenon that occurs at lower current densities for melts with lower bulk anhydride concentrations.…”

Development of a thermodynamic approach to assist the control of the precipitation of hydroxyapatites and associated calcium phosphates in open systems

“…[44][45][46][47] Note that, for ACP, the thermodynamic data used in this study are those associated with the β-Ca 3 (PO 4 ) 2 mineral having a close structure. 48 (b) Data on the acid-base equilibria involving phosphate species at 80 °C were extrapolated from the study of Rard and Wolery, 49 using the Ellingham approximation. 50…”

Benson group additivity values of phosphines and phosphine oxides: Fast and accurate computational thermochemistry of organophosphorus species

“…It is therefore not surprising that many older thermochemical reference values have been shown to be unreliable or erroneous. For example, incorrect standard enthalpies of formation of some orthophosphates have been given in the National Bureau of Standards (NBS) tables, and data using red, not white, phosphorus as the elemental reference has not always been corrected for modern standards …”
