The mean force potential of interactions between the products of the dissociation of NaCl in water microdroplets was calculated with allowance for the thermal contact and exchange of molecules with vapor by the Monte Carlo method using many-particle interaction model developed in a previous work. The states of recombined and nonrecombined ions in a cluster are divided by a free-energy barrier with a height of up to 40 k BT, which is an order of magnitude higher than in bulk aqueous electrolytes, but twofold as lower than the products of HCl decomposition under the same conditions. Depending on the relative humidity, NaCl is present in water vapors in the form of unpaired hydrated ions or nonrecombined ion pairs stabilized in water clusters at an interionic spacing of about 16 A. The spatial distribution of molecules in the interionic spacing is characterized by the ellipsoid of revolution with cross section of about 4 A.
