CLEAR & SIMPLE - Solubility of Substances - What Changes the Solubility of a Substance - Solubility Curves - Saturated, Unsaturated, Supersaturated Solutions. This video explains the factors that affect solubility. The video explains the relationship between heat-temperature and solubility, pressure and solubility, surface area and solubility, agitation-shaking and solubility and the type of solvent, ionic, polar covalent, nonpolar covalent.
