Solubility refers to the ability of a substance, known as the solute, to dissolve in a solvent to form a homogeneous mixture called a solution. This property is fundamental in chemistry, biology, and various industrial processes, influencing reactions, separations, and material properties. The extent of solubility depends on factors such as temperature, pressure, and the nature of the solute and solvent, including their chemical structure and polarity.

Solubility is typically expressed quantitatively as the maximum amount of solute that can dissolve in a given amount of solvent at a specified temperature. For example, solubility is often measured in grams of solute per 100 milliliters of solvent. Common units include molarity (moles per liter) or molality (moles per kilogram of solvent). Solubility curves, which plot solubility against temperature, illustrate how solubility changes with thermal energy.

The process of dissolution involves breaking intermolecular forces in both the solute and solvent, allowing solute particles to disperse evenly throughout the solvent. Like dissolves like is a general guideline: polar solutes tend to dissolve in polar solvents (e.g., water), while nonpolar solutes dissolve in nonpolar solvents (e.g., oils). Exceptions exist due to other interactions, such as hydrogen bonding or ion-dipole forces.

Solubility plays a critical role in everyday life and technology. For instance, it affects the preparation of medications, food flavoring, and cleaning agents. In environmental science, solubility influences the behavior of pollutants in water. Understanding solubility helps in designing extraction methods, crystallization processes, and even biological systems, where molecular transport relies on solubility principles.
