The luster of the surface of the aluminium utensils in the house is lost after a few days. Why does this happen?

Text Solution

Verified by Experts

This happens due to oxidation reaction. Aluminium utensils, which are used for a long time lose their luster due to the formation of a thin layer of aluminium oxide `(Al_2O_3)` on their surface.
