Lesson: Water of Crystallization Chemistry

Students will be able to

• define and understand the term water of crystallization,
• understand that salts can be hydrated or anhydrous,
• understand the use of dot notation to express water of crystallization,
• calculate the stoichiometry of a hydrated crystal based on hydrated and dehydrated masses of a crystal,
• connect the loss of mass of a hydrated crystal with the loss of water molecules from the crystal,
• describe in brief the properties of different hydrates (e.g., efflorescence, hygroscopicity).
