Evaporation Experiment

Evaporation Experiment 
For chemicals and chaos we have been learning about evaporation, evaporation is when liquid turns into gas, for example if a liquid is heated up to its boiling point it will evaporate and turn into a gas.

Aim:
We are doing this experiment to learn more about evaporation and to learn how it works and what will happen to the copper sulfate.

Hypothesis:
I think that we will see some gas and some of the copper sulfate will evaporate.

Equipment: Copper sulfate solution, 250mL beaker, Heat proof mat, evaporating basin, element.

Method:

  1. Set up the element 
  2. Add 100mL of hot water to the beaker and place on the element 
  3. Add copper sulfate to the evaporating basin till its a quarter full
  4. Carefully, place the evaporating basin on top of the beaker
  5. Turn on the element to 8
  6. Heat the solution until most of solvent has been evaporated and crystals of solute are forming.
  7. Turn off element- careful not to touch as will be hot for a long time.

Observation: As time goes by we see that inside the beaker there where bubbles forming, and maybe a few drops of water & you can slightly hear the small bubbles popping or the sound of boiling happening.

Conclusion: The experiment did not work as the element we were using didn't heat it up enough.

Evaluation: It was fun but, it didn't go as planned but now we see that we may need to adjust some things next time around.
