Solvation is the process in which solvent molecules surround and interact with solute particles, helping to dissolve them. This interaction occurs when the attractive forces between the solvent and solute are strong enough to overcome the forces holding the solute particles together. Common examples of solvents include water, ethanol, and acetone, while solutes can be salt, sugar, or gases. The effectiveness of solvation depends on factors such as temperature, pressure, and the nature of the solvent and solute. Polar solvents, like water, are particularly good at dissolving polar solutes, while nonpolar solvents, such as hexane, are better suited for nonpolar solutes. Understanding solvation is essential in fields like chemistry and pharmacology.
