Abstract (English):
The algorithm for the calculation of equilibrium constants in systems containing a lot of precipitations was suggested. For the calculation of the formation of precipitation areas used four conditions saturation of the solution: 1. Rule of solubility 2. Rule molecular solubility 3. Rule solubility intermediates, 4. The condition of the sedimentation priority. This methodology is used to construct a mathematical model of the equilibrium in the system SnSO 4 – H 2O – OH – as the function of pH and the concentration Sn(II) . A mathematical model of the system is designed to optimize the synthesis of desired compounds.
