Crystals of copper sulphate are heated in a test tube for some time. What is the source of liquid droplets seen on the inner upper side of the test tube during the heating process?
(N/A) Crystals of copper sulphate $(CuSO_{4} \cdot 5H_{2}O)$ contain water of crystallisation.
Upon heating,these crystals lose their water of crystallisation and turn white (anhydrous).
This released water evaporates and condenses as liquid droplets on the cooler inner upper side of the test tube.
