The chemical equation Al + HCl -> AlCl3 + H2

  1. Detailed information about the Al + HCl -> AlCl3 + H2equation:

    • The left side of the equation is aluminum (Al) and hydrochloric acid (HCl).
    • The right side of the equation is aluminum chloride (AlCl3) and hydrogen (H2).
    • Al and HCl are the reactants, AlCl3 and H2 are the products.
    • This is a redox reaction. Aluminum is oxidized (from oxidation state 0 to 3+) and hydrogen is reduced (from oxidation state 1+ to 0).

  2. Reaction conditions:

    • The condition for this reaction requires a sufficiently concentrated HCl acid.
    • The reaction is usually carried out at room temperature.

  3. Reaction process:

    • Aluminum reacts with hydrochloric acid to form aluminum chloride and hydrogen gas.
    • The number of moles of reactants and products must follow the law of conservation of mass.

  4. Phenomena occurring:

    • When aluminum is added to a solution of hydrochloric acid, hydrogen gas bubbles will be generated and solution will become cloudy due to the precipitation of the aluminum chloride product.
    • This phenomenon indicates that the reaction has occurred.
