The chemical equation BaSO4 + 2HCl -> BaCl2 + H2SO4

  1. Detailed information about the equation BaSO4 + 2HCl -> BaCl2 + H2SO4:

    • BaSO4 (Barium sulfate) and HCl (hydrochloric acid) are the reactants, producing BaCl2 (Barium chloride) and H2SO4 (sulfuric acid) as products.
    • BaSO4 is commonly known as barium sulfate, a white solid that is insoluble in water. HCl is a strong acid, widely used in industrial chemistry.
    • BaCl2, barium chloride, is a complex compound of barium and chlorine. H2SO4, sulfuric acid, is a strong acid involved in many different industrial processes.

  2. Reaction conditions:

    • This reaction needs to be carried out in an acidic environment (due to the presence of HCl) and at high temperatures to accelerate the reaction process.

  3. Reaction process:

    • During the reaction process, the Ba2+ ion from BaSO4 will separate and combine with the Cl- ion from HCl to form BaCl2.
    • The SO42- ion from BaSO4 will also separate and combine with the H+ ion from HCl to create H2SO4.

  4. Phenomena observed:

    • When the reaction occurs, it should be noted that we cannot see any direct physical changes as all the participating substances and products are in liquid form or soluble in water. However, if you can measure the change in acid concentration, you will see that the concentration of HCl decreases while the concentration of H2SO4 increases.
