Question
State the property of the metal being utilized in the following :
| Use of metal | Property |
| Zinc in Galvanization | |
| Aluminium in Thermite welding |
Solution
| Use of metal | Property |
| Zinc in Galvanization | Zinc oxidises more readily than iron, thus preventing the rusting of iron. |
| Aluminium in Thermite welding | Aluminium is a good reducing agent. |
