The chemical equation BaS + HCl -> BaCl2 + H2S

  1. Detailed information about the equation BaS + HCl -> BaCl2 + H2S

    • BaS is Barium sulfide, a chemical compound with the chemical formula BaS. It usually appears as a white powder and is an insoluble solid in water.
    • HCl, hydrochloric acid, is a colorless, odorless, highly toxic and corrosive liquid. It completely dissolves in water to form a strong acid solution.
    • BaCl2, Barium chloride, is a chemical compound with the chemical formula BaCl2. It appears as white crystals and is a soluble solid in water.
    • H2S, Hydrogen sulfide, is a colorless gas, heavier than air and has a distinctive rotten egg smell. It is insoluble in water.

  2. Reaction conditions
    The reaction occurs under normal temperature and pressure conditions.

  3. Reaction Process
    Barium sulfide reacts with hydrochloric acid to form Barium chloride and Hydrogen sulfide. This reaction process is described by the chemical equation: BaS + 2HCl -> BaCl2 + H2S.

  4. Phenomena occurring
    When the reaction occurs, the release of Hydrogen sulfide gas can be observed, characterized by its distinctive rotten egg smell.
