The equation Fe + 2H2SO4 -> Fe2(SO4)3 + H2

  1. Detailed information about the equation Fe + 2H2SO4 -> Fe2(SO4)3 + H2:

    • This equation describes the reaction between iron (Fe) and concentrated sulfuric acid (H2SO4) to form iron (III) sulfate (Fe2(SO4)3) and hydrogen (H2).

    • In this equation, iron and sulfuric acid are the reactants, iron (III) sulfate and hydrogen are the reaction products.

  2. Reaction conditions:

    • For the reaction to occur, there needs to be contact between iron and sulfuric acid.

    • The sulfuric acid needs to be in a concentrated form.

    • The reaction will occur more effectively at high temperatures.

  3. Reaction process:

    • When iron comes into contact with sulfuric acid, iron is oxidized to iron (III) and the sulfuric acid is reduced to hydrogen.

    • The essence of the reaction is the displacement between the iron ion and the hydrogen ion in sulfuric acid.

  4. Observed phenomena:

    • When the reaction occurs, iron will dissolve in sulfuric acid.

    • We will see hydrogen gas rising.

    • After the reaction, the solution will contain iron (III) sulfate, which is reddish-brown in color.
