Question

Action of heat on blue vitriol is a physical as well as chemical change. Justify.

Answer 1

Answer:

Blue Vitriol is hydrated Copper Sulphate.

When blue vitriol is heated, it undergoes a physical change. This physical change is evident from the fact that we get white powder on heating hydrated copper sulphate. This happens because the water present in blue vitriol vaporises and what is left is an anhydrous element.
