Abstract

By classical molecular dynamics, a series of solutions in the ternary water-lithium nitrate-calcium nitrate system is simulated. The radial distribution functions for different atom pairs are calculated, the coordination numbers are estimated, and the pattern of change of their first solvation shell composition with a change in the component ratio in the model system is examined. The first sphere of water molecule in the solutions with different concentration is considered in detail. Eight main structural types of the nearest-neighbor water molecule surrounding and their major features are identified, the probabilities of the occurrence of these structures in the ternary system are estimated.
