| Abstract: | Errors arising from solubility losses and co-precipitation in the gravimetric determination of fluoride by precipitation of
calcium fluoride by classical and homogeneous methods have been investigated by radiometric techniques. It is shown that co-precipitation
of chloride is the larger source of error and least in the homogeneous method. Distribution of chloride in the calcium fluoride
precipitate is shown to follow the Doerner-Hoskins distribution law. |
