The equation is Ba + 2HCl -> BaCl2 + H2

  1. Detailed information about the chemical equation Ba + 2HCl -> BaCl2 + H2:

    • This equation describes the chemical reaction process between Barium (Ba) and hydrochloric acid (HCl) to produce Barium chloride (BaCl2) and hydrogen (H2).
    • In this chemical equation, the reaction ratio between Ba and HCl is 1:2, meaning 1 mol of Ba will react with 2 mol of HCl to produce 1 mol of BaCl2 and 1 mol of H2.

  2. Reaction conditions:
    This reaction occurs under normal temperature and pressure conditions.

  3. Reaction process:

    • Step 1: Ba reacts with HCl to produce BaCl2.
    • Step 2: The product BaCl2 continues to react with HCl to produce H2.

  4. Observed phenomena:
    When the reaction happens, one can observe the following phenomena:

    • Ba dissolves in the HCl solution, producing a BaCl2 solution and causing the solution to become cloudy white.
    • H2 gas is released, which can be easily identified by burning this gas. H2 will burn with a faint blue flame.
