What is solubility?
Short answer
Solubility is the maximum amount of a solute that dissolves in a given amount of solvent at a specific temperature, forming a saturated solution. A solution below this limit is unsaturated; one held above it is supersaturated and unstable. Solubility depends on the nature of solute and solvent, temperature, and — for gases — pressure.

Frequently asked questions
- What is a saturated solution?
- One holding the maximum solute that can dissolve at that temperature; any extra solute stays undissolved.
- How does temperature affect solubility?
- For most solids, solubility rises with temperature; for gases, it falls as temperature increases.
