摘要：Experimental investigate the process of evaporation of water-salt solutions on the horizontal heating surface at a temperature of 90 °C. It was revealed that there are differences in the process of evaporation of hydrous solutions of salts forming and not forming water-salt hydrates. The absence of hydrates of salts in hydrous solutions NaCl, CaCl2and CsCl made it possible to fix the rate of formation of a solid phase (nucleation) in the volume of the supersaturated solution.
