Recently, we have reported an unusual phenomenon occurring at the polarized interface between two immiscible electrolyte solutions (ITIES), which is characterized by the anomalous salt extraction seemingly violating the classical partition law [1]. The preliminary results indicated that this extraction is probably driven by the formation of the hydrated salt clusters in the organic solvent phase [1]. Accumulation of water clusters may finally result in the formation of a water-in-oil emulsion [2]. Spontaneous emulsification at liquid/liquid boundaries can be of the great practical significance for separation, pharmaceutical, chemical, foods, and cosmetic applications [3]. Related studies have dealt with the structure and stability of water clusters [4, 5], and the hydration of ions [6, 7], in the hydrophobic polar solvent like nitrobenzene (NB) or 1,2-dichloroethane (DCE)...
