White anhydrous copper sulphate turns blue in the presence of water. In which test is this useful?

Answer and explanation

Correct answer: Test for the presence of water

Anhydrous copper sulphate is white because it lacks water of crystallisation. When water is present, it becomes hydrated copper sulphate, CuSO4·5H2O, which is blue. This clear colour change makes it a useful qualitative test for water or moisture. Thus option A is correct; oxygen, hydrogen and chlorine require different chemical tests and do not cause this characteristic change.
