Solubility

Solubility is a measure of the maximum amount of solute that can dissolve in a solvent at a given temperature. It is a characteristic property of the solute-solvent combination and is expressed in terms of the amount of solute that can be dissolved in a given amount of solvent to form a saturated solution.

Factors Affecting Solubility

The solubility of a solute in a solvent can be influenced by several factors:

Temperature: In general, the solubility of solids in liquids increases with an increase in temperature, while the solubility of gases in liquids decreases with an increase in temperature.
Pressure: The solubility of gases in liquids is directly proportional to the pressure of the gas above the liquid. An increase in pressure leads to an increase in the solubility of the gas.
Nature of the solute and solvent: The chemical nature of the solute and solvent also affects solubility. "Like dissolves like" is a general rule which means polar solutes tend to dissolve in polar solvents and nonpolar solutes tend to dissolve in nonpolar solvents.

Units of Solubility

The solubility of a substance is often expressed in either grams of solute per 100 grams of solvent (g/100g) or in moles per liter of solution (mol/L).

Applications of Solubility

Solubility plays a crucial role in various fields such as chemistry, pharmacy, environmental science, and manufacturing. Understanding the solubility of different substances is important for processes like drug formulation, pollution control, and product development in industries.
