    This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at list of inorganic compounds . There is no complete list of chemical compounds since by nature the list would be infinite.

  5. Barium - Wikipedia

    en.wikipedia.org/wiki/Barium

    The most common minerals of barium are barite (barium sulfate, BaSO 4) and witherite (barium carbonate, BaCO 3). The name barium originates from the alchemical derivative "baryta", from Greek βαρὺς (barys), meaning 'heavy'. Baric is the adjectival form of barium. Barium was identified as a new element in 1772, but not reduced to a metal ...

  6. Barium sulfate - Wikipedia

    en.wikipedia.org/wiki/Barium_sulfate

    Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4. It is a white crystalline solid that is odorless and insoluble in water. It occurs in nature as the mineral barite, which is the main commercial source of barium and materials prepared from it. Its opaque white appearance and its high density are exploited ...

    en.wikipedia.org/wiki/Standard_Gibbs_free_energy...

    The standard Gibbs free energy of formation (G f °) of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 °C).

    Thus, it forms barium sulfate and barium phosphate with sulfuric and phosphoric acids, respectively. Reaction with hydrogen sulfide produces barium sulfide . Precipitation of many insoluble, or less soluble barium salts, may result from double replacement reaction when a barium hydroxide aqueous solution is mixed with many solutions of other ...
