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:
- Set up the element
- Add 100mL of hot water to the beaker and place on the element
- Add copper sulfate to the evaporating basin till its a quarter full
- Carefully, place the evaporating basin on top of the beaker
- Turn on the element to 8
- Heat the solution until most of solvent has been evaporated and crystals of solute are forming.
- 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.
