Water Films: The Motor of Phase Transitions in Salt Mixtures.

ABSTRACT: The interaction of water vapor with soluble electrolytes has been comprehensively studied due to their ubiquity in nature and industry. Enormous experimental works have elucidated the mechanisms of water molecule adsorption, layer growth, and ion solvation in the water film on a NaCl crystal surface. In this study, we employ a new method to investigate the moisture uptake behavior on the NaCl crystal surface under varying humidity levels by using environmental scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (ESEM-EDX). Additionally, water vapor sorption, ESEM, and Raman microscopy are used to examine the role of water films in facilitating phase transitions and chemical reactions of salt mixtures. Our results indicate that the water uptake on a NaCl crystal s
