The chemical equation Cu2O + 2H2SO4 -> 2CuSO4 + 2H2O

  1. Detailed information about the equation Cu2O + 2H2SO4 -> 2CuSO4 + 2H2O:

    • This equation describes the chemical reaction process between copper(I) oxide (Cu2O) and sulfuric acid (H2SO4) to form copper(II) sulfate (CuSO4) and water (H2O).
    • According to the balanced equation, 1 mole of copper(I) oxide reacts with 2 moles of sulfuric acid to produce 2 moles of copper(II) sulfate and 2 moles of water.

  2. Reaction conditions:

    • The reaction requires the presence of specific temperature and pressure.
    • It is necessary to ensure that copper(I) oxide and sulfuric acid are directly and fully connected for the reaction to proceed smoothly.

  3. Reaction process:

    • Copper(I) oxide and sulfuric acid react with each other to produce copper(II) sulfate and water.
    • This process is also accompanied by the release of heat, therefore, if performed under laboratory conditions, an increase in temperature can be observed.

  4. Phenomena occurring:

    • When the reaction occurs, the initial red color of copper(I) oxide will gradually disappear, replaced by the appearance of the blue color of copper(II) sulfate.
    • If the reaction is performed in a test tube, the increase in heat as well as the creation of steam can be observed.
