Instructional Ideas
- Extend the lesson by asking learners to calculate the change in enthalpy as the solid is rehydrated
- Perform the lab as a demonstration, highlighting copper (II) sulfate's ability to serve as a test for water in a solution
Classroom Considerations
- Pair pupils for the experiment
- Make sure the class is monitoring the amount of water produced and can carefully move the delivery tube to prevent the water being pulled back in to the reaction vessel
Pros
- The equipment setup diagram is very helpful for students with less experience in the lab
- Activity is a great way to illustrate the differences between hydrated and anhydrous compounds
Cons
- None
