Which of the following element is used in the process of galvanization?

The correct answer is Zinc.

Key Points

• Zinc is the primary element used in the process of galvanization.
• Galvanization is a method used to protect iron and steel from rusting.
• During galvanization, a layer of zinc is applied to the surface of the metal.
• Zinc's natural resistance to corrosion helps prevent the underlying metal from rusting.

Additional Information

• Hot-dip Galvanization
  • In this process, the metal is dipped into a bath of molten zinc.
  • This method creates a thick, durable layer of zinc on the surface.
• Electro-galvanization
  • This process uses an electric current to deposit a thin layer of zinc.
  • It is often used for smaller items like screws and nails.
• Corrosion Protection
  • Zinc acts as a sacrificial anode, meaning it will corrode first before the iron or steel does.
  • This property significantly extends the lifespan of galvanized materials.
• Applications of Galvanized Metals
  • Galvanized steel is commonly used in construction, automotive, and electrical industries.
  • Examples include roofing materials, car bodies, and electrical boxes.
