Löslichkeits
Löslichkeit refers to the ability of a substance, the solute, to dissolve in another substance, the solvent, to form a homogeneous solution. It is typically expressed as the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature and pressure. Factors influencing solubility include the nature of the solute and solvent, temperature, and pressure. Generally, "like dissolves like," meaning polar solutes dissolve well in polar solvents, and nonpolar solutes dissolve well in nonpolar solvents. Increasing temperature usually increases the solubility of solids in liquids, but can decrease the solubility of gases in liquids. Pressure has a significant effect on the solubility of gases; higher pressure leads to higher gas solubility. When a solution contains the maximum amount of solute it can hold at a given temperature, it is said to be saturated. A solution with less solute than saturation is unsaturated, and one with more solute than saturation is supersaturated, which is an unstable state. Solubility is a crucial concept in chemistry, biology, and many industrial processes, affecting reactions, separations, and the behavior of substances in various environments.
