Give reason.
Copper and brass utensils should be tinned.
उत्तर
Copper and brass materials also undergo corrosion, resulting in the formation of a greenish layer on this surface. When the surface of copper or brass is contacted by air or water, it results in corrosion, and to prevent this, the process of tining is used. In this process, copper and brass articles are coated with tin.
