The equation Cu + 2HgSO4 -> CuSO4 + 2Hg

  1. Detailed information about the chemical equation:
    The chemical equation represents the reaction between copper (Cu) and mercury(II) sulfate (HgSO4) to produce copper(II) sulfate (CuSO4) and mercury (Hg).

  2. Reaction conditions:
    This reaction takes place under normal temperature conditions and does not require a catalyst. However, the reaction rate may increase as the temperature rises.

  3. Reaction process:
    When copper is introduced into a solution of mercury(II) sulfate, it reacts with the mercury(II) sulfate to produce copper(II) sulfate and mercury. Copper shifts from an uncoordinated state (not combined with any other compounds) to a coordinated state (combined with another compound), in this case, it’s with SO4 to form CuSO4.

  4. Occurred phenomenon:
    When the reaction occurs, you will see copper being released from the surface and turning into the blue color of copper(II) sulfate. Copper exhibits good corrosion resistance, therefore, it does not dissolve in the solution of mercury(II) sulfate until the reaction occurs. On the other hand, the mercury produced during the reaction will appear in the form of white silver particles.
