Examples of galvanize in the following topics:

  • Free Energy and Cell Potential

    • In a galvanic cell, where a spontaneous redox reaction drives the cell to produce an electric potential, the change in Gibbs free energy must be negative.
    • The basis for an electrochemical cell, such as the galvanic cell, is always a redox reaction that can be broken down into two half-reactions: oxidation occurs at the anode, where there is a loss of electrons, and reduction occurs at the cathode, where there is a gain of electrons.
    • In a galvanic cell, where a spontaneous redox reaction drives the cell to produce an electric potential, the change in Gibbs free energy must be negative.
    • If E°cell > 0, then the process is spontaneous (galvanic cell)
  • Preventing Corrosion

    • The corrosion-prone iron alloy steel is commonly coated with zinc, a more active metal, in a process known as galvanizing.
    • Galvanic sacrificial anode attached to the hull of a ship; here, the sacrificial anode shows corrosion but the metal it is attached to does not.
    • The galvanic anode continues to corrode, consuming the anode material until eventually it must be replaced, but the cathodic material is protected.
    • Protecting iron alloys with a coating of a more active metal through the process of galvanizing prevents the alloys from corroding.
