The equation Mg + 2HCl -> MgCl2 + H2

  1. Detailed information about the equation Mg + 2HCl -> MgCl2 + H2

    • The above equation represents the reaction between Magnesium metal (Mg) and Hydrochloric acid (HCl) to produce Magnesium chloride salt (MgCl2) and Hydrogen (H2).

  2. Reaction conditions

    • This reaction occurs under normal conditions, which means it happens under usual environmental conditions such as temperature, pressure without the need for modification.

  3. Reaction process

    • Magnesium reacts with hydrochloric acid to produce MgCl2 and Hydrogen gas.
    • In the reaction process, Magnesium will lose 2 electrons to form Mg2+ ion, which combines with Chloride ion to form Magnesium chloride.
    • Hydrogen from hydrochloric acid receives 2 electrons to form Hydrogen gas.

  4. Observations

    • When Magnesium is added to a solution of hydrochloric acid, white gas bubbles are seen being released. This is Hydrogen gas.
    • At the same time, the solution becomes transparent due to the formation of Magnesium chloride, a salt that is colorless.
