Procedure:

PART 1: ANALYSIS OF COPPER (II) SULFATE PENTAHYDRATE 1. Heat an empty crucible and bring it to a constant mass (0.0010 g). In order to do this, record the mass of the empty crucible. Then heat the crucible for 3-4 minutes. Note that the surface of the hot plate reaches ~500 C when it is turned on all the way. Go low and slow and keep the temperature of the hot plate lower than 250 C. 2. Cool the crucible on the lab bench and record its dry mass. Handle the microcrucible with crucible tongs (it is very hot!). For winter 2022, you may heat the microcrucible only once to ensure excess water has been removed. Make sure that you record the dry mass of the microcrucible in your lab notebook. 3. Add approximately 1.00 grams of copper(II) sulfate pentahydrate to the micro-crucible. Measure the mass of the micro-crucible with the solid. Record this value in your lab notebook. 4. Heat the micro-crucible over a hot plate until the blue color is gone. 5. Cool the micro-crucible to room temperature and measure the mass of the micro-crucible with the anhydrous compound. Record this value in your lab notebook. 6. Discard the contents of the micro-crucible in the appropriate waste disposal container. Double check with your instructor if you are unsure which waste container to use.

Draw a picture/scheme of the lab procedure on a piece of paper. Visualize what you will do in the lab, and make your picture as detailed as possible.
