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.

Poly(styrene) has a solubility parameter of 9.1 cal 1/2 cm −3/2, and thus ethyl acetate is likely to be a good solvent. Nylon 6,6 has a solubility parameter of 13.7 cal 1/2 cm −3/2 , and ethanol is likely to be the best solvent of those tabulated.
The drugs are classified in BCS on the basis of solubility and permeability. Solubility class boundaries are based on the highest dose strength of an immediate release product. A drug is considered highly soluble when the highest dose strength is soluble in 250 ml or less of aqueous media over the pH range of 1 to 6.8.
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.
Sodium chlorate is an inorganic compound with the chemical formula Na ClO 3.It is a white crystalline powder that is readily soluble in water. It is hygroscopic.It decomposes above 300 °C to release oxygen [4] and leaves sodium chloride.
Cerium(III) sulfate, also called cerous sulfate, is an inorganic compound with the formula Ce 2 (SO 4) 3. It is one of the few salts whose solubility in water decreases with rising temperature. [1] Cerium(III) sulfate is a hygroscopic white solid, which begins to decompose above 600°C. It has a monoclinic crystal structure.
