Dynamic method at a volume flow rate of dry nitrogen 1 l/hour in the experimental plant determined the equilibrium partial pressures of ammonia and water vapor above the 2.87 mol / l ammonia solutions tetraammiakats zinc and copper at temperatures of 293-353K. The reliability of the results identified in the study of pressure over pure ammonia water with a concentration of 2.87 - 13.34 mol / L NH3 in the temperature interval 293 - 343 K. The obtained results in good agreement with the reference values​​, the systematic error does not exceed 0.15%. Field study partial pressure adequate concentrations of dissolved zinc and copper of 0 to 0,535, and from 0 to 0.284 mol / l, respectively, the concentration of ammonium chloride - from 0.34 to 2.82 mol / l. The nature of the changes and the partial pressures of ammonia and water activity in the concentration range studied, and temperature. The enthalpies of vaporization of the solution containing copper and zinc ammine.
