Evaporation Experiment

                      Separating a Mixture using Evaporation

Aim: We are trying to separate the mixture so it will end up on something solid and without liquid on it.
Hypothesis: I think after this experiment the liquid on the mixture will evaporate.
Equipment: Copper sulfate solution, 250mL Beaker, heat proof mat, evaporating basin, element. 
Method:
Set up element
  1. Add 50mL of hot water to the beaker and place on the element.

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

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

  1. Turn on the element to 8

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

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

  1. Turn off the heat - careful not to touch the equipment as it will be hot for a long time.

Observations:  Once we put our mixture on the stove and the water starter to boil the sulfate started to smell weird and the copper sulfate was slowly turning into crystals and there was also steam.

Conclusion: In the end of the experiment the small part of the copper sulfate that we used turned to a solid and water started to evaporate.

Discussion: The purpose of this experiment is to evaporate the water and to observe if the copper sulfate will turn into crystals.

Evaluation: I think our experiment worked but for me it's better if we observe it more, since we didn't observe it that much because we are running out of time we probably miss some of the process that is happening while the water is boiling and how the copper sulfate turns into crystals.
