Evaporation Experiment

Hello everyone today we are doing evaporation while doing the experiment we are looking at the changes in the water and also see the evaporating basin. The experiment was fun because we used bunsen burner, I had to lit a fire by a lighter. The water was condensing, steaming, boiling and evaporating. At the bottom are the aim, hypothesis and the equipment used. 

Separating a Mixture using Evaporation:

Aim: why you are doing the experiment

To separate a solution into a solvent and solute using evaporation.

Hypothesis: what you think will happen, and why….

I think it will heat up and the copper sulfate will leave some crystal at the sides.

Equipment: Copper sulfate solution, 250mL Beaker, heatproof mat, evaporating basin, element. 

Method: 

1. Set up element

2. Add 100mL of hot water to the beaker and place on the element.

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

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

5. Turn on the element to 3

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

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

Observations: What did you see, hear etc when doing the experiment.

The boiling was loud so you could hear the boil of the water and also you can hear the gas.

Conclusion: Was your hypothesis correct?

yes, the crystal stayed and it has some a little bit of kinda glitter.

Discussion: What happened and why… using your scientific keywords (Evaporating, Solvent, solute, solution, mixture, heat, boil) The water started boiling because of the heat and while it was boiling the steam started coming out of the beaker. When it

Evaluation: Did you enjoy the experiment? Why? What would you do differently next time? 

I enjoyed it because I'm learning something new and I had fun with my group but some people in our group sometimes don't really do anything so I would like to change it.

Copper sulfate is poisonous
