Solubility

Solubility refers to the ability of a substance, called a solute, to dissolve in another substance, known as a solvent, creating a homogeneous mixture called a solution. For example, when sugar dissolves in water, the individual sugar molecules spread out evenly among the water molecules. Solubility is influenced by factors such as temperature, pressure, and the nature of the solute and solvent. Some substances, like salt, are highly soluble in water, while others, like oil, are not. Understanding solubility is essential in many fields, including chemistry, biology, and environmental science, as it affects processes like digestion and pollution.
