Abstract
The Filippov's eutonic method was applied to the study of M2HPO3-H3PO3-H2O heterogeneous systems (M = Li, Na, K) at 25 °C. The values of the standard Gibbs energy changes for the reactions occurring in these systems were obtained. The highest changes in the Gibbs energy accompany the formation of hydrogenphosphites M(H2PO3), the energy increases from Li to K and decreases from hydrogenphosphite to tris(orthophosphite) and bis(orthophosphite).
