Question
State whether the following statement is true or false:
Copper sulphate crystals are always wet due to the presence of water of crystallisation in them.
Advertisements
Solution
This statement is false.
Explanation:
Copper sulphate crystals contain water of crystallisation, but this water is chemically bound within their solid structure rather than being free liquid water. Consequently, the crystals look and feel completely dry to the touch. This bound water is only responsible for giving the crystals their fixed geometric shape and brilliant blue colour.
