Abstract The ionic product of 10750oxy-apatite has been calculated from data sets from the hard water rivers Rhine and Rhone. An overall value of 10−50 has been obtained, but this value has an uncertainty due to the uncertainty of the third ionisation constant of phosphoric acid. Implicitly it has been shown that these rivers are saturated with respect to 10750oxy-apatite and that thus calcium controls the solubility of o-phosphate.
