Abstract
The solubility of aged iron(III) hydroxide precipitates was investigated by determining [Fe3+] and [H+] of solutions in contact with the solid phases. [Fe3+] and [H+] were measured by the EMF.‐method at the constant ionic strength 3M (Na)C104. The precipitates were investigated by X‐ray and electron microscope methods. The following equilibrium constants were derived: magnified image
