Question

explain observation made when anhydrous calcium chloride and anhydrous copper (ii) sulphate are separately exposed to the atmosphere for about two days​

Answer 1

Anhydrous calcium chloride dissolves and becomes liquid

Anhydrous copper (ii) sulphate will produce crystal particles

Step-by-step explanation:

Anhydrous calcium chloride is deliquescent and hence when it is exposed to air, it absorbs water from air. After absorbing water, it dissolves and after some time a pool of clear liquid appears.

Anhydrous copper (ii) sulphate will form crystal structures and the following reaction will takes place

CuSO4 + 5 H20 --> CuSO4.5H2O
