Abstract

The oxygen exchange between phosphoric acid and water at various temperatures and concentrations has been investigated in the presence and absence of K2HPO4. The minimum rate of exchange is observed for a solution concentration of 2–2.5 mole/l. It has been shown that in concentrated solutions of phosphoric acid the formation of H4PO 4 + is possible, and the true rate constant of the acid-catalytic conversion and the basicity constant of H3PO4 has been calculated. It has been found that in a solution where the mobility of the oxygen atom towards the anion increases, the value of the limiting current on the anodic dissolution of copper diminishes.
