The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Solubility equilibrium – Thermodynamic equilibrium between a solid and a solution of the same compound; Total dissolved solids – Measurement in environmental chemistry is a common term in a range of disciplines, and can have different meanings depending on the analytical method used. In water quality, it refers to the amount of residue ...
BCS classes. According to the Biopharmaceutics Classification System (BCS) drug substances are classified to four classes upon their solubility and permeability: [1] Class I – high permeability, high solubility. Example: metoprolol, paracetamol [2] Those compounds are well absorbed and their absorption rate is usually higher than excretion.
A solubility equilibrium exists when a chemical compound in the solid state is in chemical equilibrium with a solution containing the compound. This type of equilibrium is an example of dynamic equilibrium in that some individual molecules migrate between the solid and solution phases such that the rates of dissolution and precipitation are equal to one another.
The first solvation shell of a sodium ion dissolved in water. An aqueous solution is a solution in which the solvent is water.It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula.
What determines a substance's solubility (briefly, main article being solution), including a passing mention of factors such as temperature and/or pressure (for the case of gases) Applications of solubility in chemical processes, and everyday life e.g. making milk from powdered milk; Comments please! --Rifleman 82 16:52, 2 January 2007 (UTC)
