Solubility is defined as which of the following?

• A. The rate at which a solute dissolves.
• B. The amount of solute that can dissolve in a solvent at a given temperature.
• C. The color of the solution.
• D. The volume of solvent present.

Answer: (B)

Solubility describes how much of a substance can dissolve in a solvent at a specific temperature. It is the maximum amount of solute that can dissolve before the solution becomes saturated. This is different from the rate at which dissolution occurs, which is about how fast the solute dissolves, and from the color or the volume of solvent. For solids, solubility generally increases with temperature, so more solute can dissolve in hotter water than in cooler water. For gases, solubility often decreases with higher temperature and increases with higher pressure. Understanding solubility helps predict whether a mixture will form a saturated solution and how much solute can be dissolved under given conditions.
