Studies on the formation of complex compounds between rare earth nitrate and uranyl nitrate. The System: Ce(NO3)3UO2(NO3)2H2O (conductance, pH, spectrophotometry, refractive‐index)

Abstract

AbstractDetermination of conductance, pH, Spectrophotometry and Refractive‐index of a series of mixed solutions of uranyl nitrate and cerous nitrate indicate, the existence of the following compounds equation image .A set of 22 mixed solutions was prepared by following NAYAR and PANDE's mono‐variation method. In all the solutions the concentration of uranyl nitrate was kept constant (i. e. M/100) while that of cerous nitrate varied systematically from 0.0 M to 0.042 M. The physico‐chemical properties, namely conductance, pH Spectrophotometry and refractive‐index were used for the investigation of complex‐compounds in the above system. When these values were plotted against the varying concentration of cerous nitrate two breaks were obtained in the regular curves at concentrations corresponding to the compound having the above formulae. The results obtained by all these physico‐chemical studies are in excellent agreement leading to the same conclusions.
