摘要：

The possible reasons for the observed greater acidity of aqueous H3PO3 vs. H3PO4 have been examined by the multiple scattering X alpha and the SCF-MO-PM3 methods. The greater acidity of H3PO3 compared to H3PO4 was found to be due to greater hydration energy of the H2PO3- ion relative to that of the H2PO4- ion. Such effect is caused by a higher partial negative charge on two of the O atoms in H2PO3- than in H2PO4-.
