Abstract
Quantitative characteristics of the nearest environment of ions in aqueous solutions of cadmium chloride and nitrate are determined by X-ray diffraction analysis in a wide range of concentrations under standard conditions. It is found that, in the studied systems, the coordination number of the cation increases with dilution from 4 to 6. The structure of solutions in the entire studied range of concentrations is determined by ionic associates of the contact type. In solutions of cadmium nitrate, the nitrate ion is monodentately coordinated to the cation.
