Study on solubility of cerium(IV) phosphate

K Li, Sirong Zhao, Jun Ma

Abstract

The solubility product constant of cerium(IV) phosphate according to the concentration of phosphate detected by spectrophotometer at pH = 0.4 and 20 degrees C were determined. The solubility product constant of cerium(IV) phosphate is 2.915 x 10(-34). The reliability of determination data is proved by s = 0.004 and CV = 1.30%. The result indicate that solubility product constant of cerium(IV) phosphate is effected by temperature and acidity significantly. Therefore, temperature and acidity increase over a particular range could result in an increase of solubility of cerium(IV) phosphate.
