Evaporation experiment

 Separating using evaporation:

Aim: To try and separate a solution into solute and solvent using evaporation. 'nuff said.

Hypothesis: The liquid will become lighter after separation.

Equipment: Copper sulfate solution, 250 ml beaker, heat proof mat, evaporating basin, element.

Method:

1. Set up element.

2. Add 100 ml of hot water to the beaker and place on the element.

3. Add copper sulfate to the evaporating basin until it is quarter full.

4. Carefully, place the evaporating basin on top of the beaker

5. Turn on the element to 3

6. Heat the solution until most of the solvent has been evaporated and crystals of solute are forming

7. Turn off the element- be careful not to touch, as it will be hot for a long time.

Observation: The element hadn't been working right, the water started boiling and the element smelled like burnt rubber incense.

Conclusion: Since the water didn't boil fast enough, I didn't notice any significant changes.

Discussion: We activated the element, the water began to boil and the steam went up to heat the evaporation basin. It began heating the basin, but nothing was fast enough to be heated and change.

Evaluation: The experiment was pretty slow and since nothing happened, was practically a waste. I didn't like the smell of the element, because I hated it. I would get a different or better heating material.
