Abstract

In this paper a study of heterogeneous systems MHPO3 -H3PO3 -H2O (M = Mg, Ca, Sr) at a temperature of 25°C using the Filippov's eutonic method has been described. Values of change in standard Gibbs energy for reactions of the studied systems have been found. Effect of the cation on hydrogen bond between the H2PO2-3 groups is discussed.
