Question

Hydrated copper sulphate is a blue crystalline solid. When heated, it changes to anhydrous copper sulphate, white powder. Which of these occur in that process?
A. Loss of water
B. Loss of oxygen.
C. Oxidation
D. Absorption of water

Answer 1

Answer is Option A - Loss of water

When blue cystals of hydrated copper sulphate is heated, the bond between copper sulphate and water breaks and thus water evaporates, This results in loss of water and the copper sulphate becomes anhydrous white powder.

Chemical formula is CuSo4.5H20 upons heating becomes CuSo4 + 5H20
