Comparisons of Measured and Theoretical Mn2+ Concentrations in Soil Suspensions1
- H. L. Bohn2
The Mn2+ concentrations in control and autoclaved suspensions of nine acid and alkaline soils in 0.01M CaCl2 differed widely from the Mn2+ concentrations calculated from models which either require measurement of Eh or assume Eh to be fixed by another redox couple. An alternative model is proposed which expresses the equilibrium solubility of the manganese compounds in terms of pH — ½pMn. The values of pH — ½pMn measured in the suspensions of all the soils tested correspond to the solubility of MnO2.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
