Aim: We are trying to separate the mixture evaporating it.
Hypothesis: it will turn to crystals
Equipment: Copper sulfate solution, 250mL Beaker, heatproof mat, evaporating basin, element.
Method:
- Set up element
- Add 100mL of hot water to the beaker and place on the element.
- Add copper sulfate to the evaporating basin until it is quarter full.
- Carefully, place the evaporating basin on top of the beaker.
- Turn on the element to 8
- Heat the solution until most of the solvent has been evaporated and crystals of solute are forming.
- Turn off the element- careful not to touch as will be hot for a long time.
Observations: It is boiling
Conclusion: yes
Discussion
Evaluation: Did you enjoy the experiment? Why? What would you do differently next time?
