Evaporation

We have been learning  about evaporation, what evaporation means is when a liquid of some sort by which water changes from a liquid to a gas or vapour. Evaporation is the primary pathway water moves from the liquid state back into the water cycle as atmospheric water vapour.

Aim: Evaporate copper sulfate ( blue liquid) = Solution.

Hypothesis: Gas formed, something will be left behind, 

Equipment: Copper sulfate solution, 250mL Beaker, heat proof mat, evaporating basin, element. 

Method: 

1. Set up element

2. Add 100mL 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 the evaporating basin on top of the beaker. 

5. Turn on the element to 4.

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

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

Oberservations: It slowly started to heat up, there was steam, started to make a powder.

Conclusion: Yes.

Discussion: What happened and why… using your scientific keywords (Evaporating, Solvent, solute, solution, mixture, heat, boil)

Evaluation: This was fun but next time I would only have one thing on the element at a time to make sure it boiled.
