Mathematic modeling of thermodynamic properties of aqua-salt systems

A method of modeling of thermodynamic properties of the solution with estimation of the range of free interaction energy values and their substitution for a distribution is proposed. In the course of modeling a concrete relation between component interaction energies and solution properties is established and the law of interaction energy distribution is chosen. The modeling scheme of the activity coefficients of salt and water in a solution with present concentration and temperature is given. The results determined for Sr(NO3)2, UO2(NO3)2, etc. are presented
