Separating a Mixture using Evaporation

 Aim: to separate a solution in to a solvent and solute using evaporation.


Equipment:

  1. Copper Sulphate solution
  2. 250ml Beaker
  3. Heat proof mat
  4. Evaporating basin
  5. Element


Method: 

  • Set up element 
  • Add 100ml of hot water to the beaker and place on the element.
  • Add copper sulphate to the Evaporating basin until it is a quarter full.
  • Carefully, place the evaporating basin on top of the beaker. 
  • Turn on the element to 3.
  • Heat the solution until most of the solvent has been evaporated and crystals of solute are forming.
  • Turn off the element, be careful not to touch, as it will be hot for a long time.


Observations:
Well the water is boiling, I can see the steam exiting out of the Beaker, also, I can see the thick bubbles, boiling inside the Beaker, and the condensation dripping one by one from the roof of the Beaker.


Discussion: 
The water that was boiling inside the Beaker, turned into crystal, because the liquid had solid in it, and then the liquid evaporated, which leaves behind crystals.

Evaluation:
I enjoyed doing this experiment with my group. What I enjoyed about this experiment, was watching the water boiling, and the condensation dripping from the top of the Beaker. Next time, I will not face my back against the Beaker, for safety, and also not putting my hand inside the Beaker.
