Water SolubilityWater solubility (SW), also know as aqueous solubility, is the maximum amount of a substance that can dissolve in water at equilibrium at a given temperature and pressure. An easy way to visualize it is to think of what the maximum amount of sugar you can dissolve in your coffee would be. SW values are usually expressed as moles of solute per liter. This parameter is used in many environmental studies to help determine the fate of chemicals in the environment. Water solubility has been correlated to the octanol-water partition coefficient (Kow), another chemical parameter used to determine the fate of chemicals in the environment. More Information
