The equation Ba(NO3)2 + 2HCl -> BaCl2 + 2HNO3

  1. Detailed information about the equation Ba(NO3)2 + 2HCl -> BaCl2 + 2HNO3:

    • This is an ion exchange reaction between barium nitrate (Ba(NO3)2) and hydrochloric acid (HCl), forming barium chloride (BaCl2) and nitric acid (HNO3).
    • This reaction can also be referred to as an ion exchange reaction or a neutralization reaction.
    • In this reaction, the barium ion (Ba+) of barium nitrate combines with the chloride ion (Cl-) of hydrochloric acid to form barium chloride, while the nitrate ion (NO3-) of Ba(NO3)2 combines with the hydrogen ion (H+) of HCl to form nitric acid.

  2. Reaction conditions:

    • This reaction can occur at room temperature.
    • Both reactants (barium nitrate and hydrochloric acid) need to be in solution form so that ions can move and combine with each other.

  3. Reaction process:

    • Initially, barium nitrate and hydrochloric acid exist as ions in solution.
    • When these two solutions meet, the barium ion and the chloride ion attract each other to form barium chloride. Simultaneously, the nitrate ion and hydrogen ion combine to form nitric acid.
    • The result is that the products of this reaction are barium chloride and nitric acid.

  4. Phenomenon that occur:

    • When barium nitrate reacts with hydrochloric acid, a solution containing barium chloride and nitric acid is created.
    • Barium chloride is colorless while nitric acid is pale yellow. Therefore, the product solution may be pale yellow.
    • If the reaction is complete, there will be no precipitate in the solution.
