Abstract : A quantitative study of the time-dependent abstraction of H(+) and OH(-) ions from solution by crystalline Fe2O3 precipitates is reported. The experimental information was gathered by potentiometric titrations of oxide suspensions, by observation of pH drift with time after rapid displacement of the pH of the solution initially equilibrated with the solid at the zpc, and by tritium exchange between the tritiated oxide and pure water.
