The chemical equation Cu + HgCl2 -> CuCl2 + Hg

  1. Detailed information about the chemical equation:

    • The above chemical equation represents the chemical reaction process between copper (Cu) and mercury(II) chloride (HgCl2) to create copper(II) chloride (CuCl2) and mercury (Hg).
    • In this equation, copper (Cu) acts as a reducing agent, helping to convert mercury(II) chloride into mercury, during this process, the copper is oxidized to copper(II) chloride.

  2. Reaction conditions:

    • The reaction occurs easily at normal temperature.
    • The reaction product can be easily separated from the solution by heating it or by allowing it to evaporate automatically.

  3. Reaction process:

    • Initially, copper and mercury(II) chloride are mixed together in a reaction solution.
    • When these two substances come into contact with each other, copper (Cu) acts on mercury(II) chloride (HgCl2), turning it into mercury (Hg) and the copper dissolves in the solution to form copper(II) chloride (CuCl2).

  4. Phenomena that occur:

    • When the reaction occurs, the color of the solution changes from the white color of mercury(II) chloride to the green color of copper(II) chloride.
    • The copper exhibits a reducing property, helping to convert mercury(II) chloride into mercury.
    • The mercury formed does not dissolve in the solution and appears as shiny droplets.
