Studies on the formation of complex compounds between transition metal nitrates and uranyl nitrate. The System: Ni(NO3)2UO2(NO3)2H2O (conductance, pH, spectrophotometry and refractive‐index)

Abstract

AbstractExperimental evidence from the values of conductance, pH, spectrophotometry and Refractive Index measurements with uranyl nitrate‐Nickel nitrate‐water system indicate two definite complex compounds in solution: magnified image A set of twenty two mixed solutions was prepared by following NAYAR and PANDE's monovariation method. In all solutions the concentration of uranyl nitrate was kept constant, (i. e. M/100), while that of nickel nitrate varied systematically from 0.0 M to 0.042 M. The physico‐chemical properties, namely, conductivity, pH, Spectrophotometry, refractive‐index, were used for the investigation of complex‐compounds, in the above system. When these values were plotted against the varying concentrations of nickel nitrate two breaks were obtained in the regular curves at concentrations corresponding to the compounds having the above formulae. The results obtained by all these physico‐chemical properties are in excellent agreement leading to the same conclusions.
