What is the water present in gypsum called?

Answer and explanation

Correct answer: Water of crystallisation

Gypsum has the formula \(\mathrm{CaSO_4\cdot 2H_2O}\). Its two water molecules occur in a fixed proportion as part of the crystal structure, so this water is called water of crystallisation. Water of constitution is bonded differently within a compound’s chemical structure, whereas \(\cdot 2H_2O\) in gypsum denotes water of crystallisation. Exam tip: \(\cdot nH_2O\) in a salt formula generally indicates water of crystallisation.
