Solubility is an attribute of a chemical substance (which may be solid, liquid or gas) known as solute to dissolve in a solid, liquid or gaseous substance known as solvent. Solutes dissolve in a solvent by breaking or dispersing to form a solution. Certain factors basically determine the solubility of a substance. The factors include; the physical and chemical properties of the solute and solvent, pressure, temperature, and availability of other chemicals.
