ELECTROMETRIC STUDIES ON THE PRECIPITATION OF HYDROUS OXIDES OF SOME QUADRIVALENT CATIONS. PART I. PRECIPITATION OF ZIRCONIUM HYDROXIDE FROM SOLUTIONS OF ZIRCONIUM SALTS
The precipitation of basic salts and hydroxide of zirconium from solutions of its sulfate, oxychloride, and nitrate was studied. Conductometric and pH titrations of the salt solutions with sodium hydroxide show that the precipitated hydroxide contains appreciable quantities of the anions. Compositions of the basic salts obtained were deduced from the titration curves. Hydrolysis of these salts was found to be a slow proeess. The increasing order of anion penetration is the same as the co-ordinating power of the respective anions, nitrate, chloride, and sulfate. Titrations of zirconium sulfate solutions against baryta show that the initially precipitated basic sulfate gives up the anion gradually with little change in the pH or the conductance and the ultimate product consists of almost pure hydroxide.
