The main commercial source of barium sulfate is the mineral baryte, which is normally highly impure. In order to produce highly pure barium sulfate, barium sulfide or barium chloride is treated with sulfuric acid: Most of the synthetic barium sulfate is used as a white pigment (together with TiO2 or ZnS) for paints.

(a) The two possible products for this combination are KNO 3 and BaSO 4 . The solubility guidelines indicate BaSO 4 is insoluble, and so a precipitation reaction is expected.

A large number of important reactions are included in three categories: precipitation, acid-base, and oxidation-reduction (redox). Precipitation reactions involve the formation of one or more insoluble products. Acid-base reactions involve the transfer of hydrogen ions between reactants. Redox reactions involve a change in oxidation number for one or more reactant elements.

We can also separate the anions by precipitating them with appropriate metal ions.

The picture shown here is the formation of solid from a gaseous solution. The equilibrium constants for saturated solution and solid formation (precipitate) are called solubility product, Ksp.
