Evaporation experiment

Experiment 

We have been learning about distillation, evaporation and dilution. Evaporation is when liquid turns into gas.

Solute- solid
Solvent- liquid
Solution- mixture
Copper sulphate-sulphur & oxygen
Aim-  To evaporate copper sulphate ( blue liquid )- solution
Hypothesis- I think that the water will bubble up and make the copper sulphate heat up and turn into gas, leaving the solid behind.
Equipment- Gauze mate, 250 ml beaker, heat proof mat, evaporating basin, element, copper sulphate solution

Method: 

1. Set up element
2. Add 100mL 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 3
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.

Observations- 
The water starts to boil up, steam is starting to come out from the top through to the evaporating dish, 
Conclusion- My hypothesis was right the water boiled up making the copper sulphate evaporate into gas/steam leaving the solid behind! Blue crystals were formed after the boiling was done.
