title: Formation constants for the complexes of orthophosphate with magnesium and hydrogen ions.
abstract: The system of orthophosphate, magnesium and hydrogen ions in aqueous solution at 25 degrees and I = 0.2M chloride has been characterized by means of glass-electrode potentiometry. Protonation constants for orthophosphate species and formation constants for the complexes MgH(2)PO(+)(4), MgHPO(4), MgPO(4)(-) and MgOH(+) are reported.
