Данная статья продолжает цикл работ авторов по исследованию дисперсной фазы воды с помощью оптического микроскопа. Ранее было обнаружено, что каждая единица дисперсной фазы представляет собой микрокристалл NaCl, окруженный толстым слоем гидратной воды, предохраняющей его от растворения. При испарении свободной воды со стеклянной поверхности осмотическое давление в остатках воды повышается, что ведет к диссоциации гидратных оболочек и контакту соли с водой. После полного испарения на стеклянной подложке остаются крупные кристаллы NaCl и гелеобразная неиспаряющаяся вода. Использование сканирующего электронного микроскопа позволило выявить ряд деталей, неизвестных ранее: образование мелких кристаллов хлорида натрия на поверхности дисперсной фазы воды и рост кристаллов на тяжах гелеобразной воды. По мнению авторов, значительная часть NaCl в высокоомной воде находится в виде кристаллов внутри дисперсной фазы, что проявляется после испарения свободной воды. Обсуждаются версии других авторов, наблюдавших «стабильные водные кластеры» в серийно разведенных растворах.

This article continues a series of works by the authors on the study of the dispersed phase of water using an optical microscope. Previously, it was found that each unit of the dispersed phase is a NaCl microcrystal surrounded by a thick layer of water of hydration, which prevents its dissolution. When free water evaporates from the glass surface, the osmotic pressure in the remaining water increases, which leads to the dissociation of hydration shells and contact of the salt with water. After complete evaporation, large NaCl crystals and gel-like non-evaporating water remain on the glass substrate. The use of a scanning electron microscope made it possible to reveal a number of previously unknown details: the formation of small crystals of sodium chloride on the surface of the dispersed phase of water and the growth of crystals on filaments of gel-like water. According to the authors, a significant part of NaCl in high-resistivity water is in the form of crystals inside the dispersed phase, which manifests itself after the evaporation of free water. The versions of other authors who observed "stable water clusters" in serially diluted solutions are discussed.
