Answer
Anhydrous
Reason — A salt which does not contain water of crystallisation is called an anhydrous salt. Since it has no water molecules attached to its crystals, it does not give water vapour on heating.
Hydrated salts contain water of crystallisation and give water vapour on heating. Hence, the correct answer is Anhydrous.
