This study investigates the key factors influencing the solubility, viscosity, and density of aqueous electrolyte systems. Model solutions of types 1-1, 1-2, 2-1, and 2-2 electrolytes were examined across a wide concentration range. The results show that solubility increases with temperature due to a higher proportion of free water molecules, while greater electrolyte concentrations lead to a rise in viscosity and density. It was found that ion radius and charge density strongly impact solution properties: larger ion radii and lower charge densities decrease viscosity and increase density, whereas smaller radii and higher charge densities have the opposite effect. The findings offer new insights into the relationship between ionic parameters and macroscopic solution behavior, supported by mathematical modeling and graphical analysis.

The solubility of electrolytes is primarily influenced by the free component of bulk water, increasing with temperature.Higher electrolyte concentrations result in increased viscosity and density due to a greater number of hydrated ions in the solution.The viscosity and density of aqueous electrolyte systems are determined by the radius and charge density of the ionic components, with smaller radii and higher charge densities increasing viscosity and decreasing density, and vice versa.

Further research should investigate the impact of varying temperature gradients on the solubility and viscosity of aqueous electrolyte solutions, potentially revealing non-linear effects not captured in this study. A detailed exploration of the structural changes in water molecules surrounding ions at different concentrations could provide a more fundamental understanding of the observed viscosity and density variations. Additionally, investigating the influence of external electric fields on the behavior of hydrated ions and their impact on solution properties could open new avenues for controlling and optimizing electrolyte solutions for various applications, such as energy storage and chemical processing. These investigations should employ advanced spectroscopic techniques and molecular dynamics simulations to complement experimental findings and provide a comprehensive understanding of the underlying mechanisms.
