Separating a Mixture using Evaporation:

Aim: To separate the solid from the liquid.
Hypothesis: I think it will boil and evaporate.

Equipment: Copper sulphate solution, 250mL Beaker, heat proof mat, evaporating basin, element. 
Method: 
  1. Set up element
  2. Add 50mL of hot water to the beaker and place on the element.
  3. Add copper sulphate 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 8
  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.

Observation: I heard the boiling water.
Conclusion: Its gonna evaporate.
Discussion: The mixture heated up and boiled then evaporated.
Evaluation: Use a bigger object to hold it.
