ELECTROMETRIC STUDIES ON THE PRECIPITATION OF HYDROUS OXIDES OF SOME QUADRIVALENT CATIONS. PART II. PRECIPITATION OF THORIUM HYDROXIDE FROM SOLUTIONS OF THORIUM SALTS
Precipitation of thorium hydroxide from thorium sulfate, chloride, and nitrate solutions by sodium hydroxide showed that when equilibria are attained, the precipitates consist of basic salts having compositions Th(OH)/sub 3.14/(SO/ sub 4/)/sub 0.43/, Th(OH)/sub 3.12/Cl/sub 0.88/, and Th(OH)/sub 3.7/(NO/sub 3/)/ sub 0.3. The anion penetration is practically of the same order in the case of sulfate and chloride, but in the case of nitrate, it is much less. Using baryta in the case of thorium sulfate solutions, it was found that although a basic salt of about the same composition is precipitated initially, it gives up its sulfate ions on addition of more of baryta, leaving behind almost pure hydrous oxide of thorium.
