When hot and concentrated, sulfuric acid is a fairly strong oxidizing agent. Write a balanced net ionic equation for the oxidation of metallic copper to Cu(II) ion by hot concentrated H2SO4, in which the sulfur is reduced to SO2.

  • Chemistry -

    Cu ==> Cu^2+ + 2e
    H2SO4 + 2H^+ + 2e ==> SO2 + 2H2O
    --------------------------
    There are the two half equations. Add them for the total net ionic equation. If you wish to make a molecular equation, you will need to add some extra sulfate ions to form CuSO4.
