Abstract
AbstractExperiments with the system Uranyl nitrate‐Lanthanum nitrate‐water viz., Conductance, pH, and spectrophotometry revealed the existence of the following compounds in solution. A set of 22 mixed solutions was prepared by following Nayar and Pande's monovariation method1. In all the solutions the concentration of uranyl nitrate was kept constant (i. e. M/200), while that of lanthanum nitrate varied systematically from 0.0M to 0.021M. The physico‐chemical properties, namely conductivity, pH, and spectrophotometry were used for the investigation of complex‐compounds in the above system. When these values are plotted against the varying concentration of Lanthanum 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.
