Answer 2

Answer:

Brass is an alloy of copper and zinc. It also undergoes corrosion when exposed to air and moisture. Brass can become oxidized due to atmospheric exposure to form a layer known as patina similar to the corrosion of copper. Hence, to prevent the formation of an oxide layer, brass and copper utensils should be tinned.
