Give Reason: Inspite of being highly reactive, aluminium is still used for making utensils.
Aluminum is used to make utensils because:
- Aluminum is a highly reactive metal. It forms aluminum oxide when it reacts with oxygen. The aluminum oxide prevents it from further corrosion as it acts as a protective layer.
- The reaction is given as : $4Al\ +\ 3O_{2}\rightarrow \ 2Al_{2} O_{3} .$
- Aluminum is a good conductor of heat.
- Aluminum is also relatively cheap.
