Evaporation Experiment

Evaporation Experiment 

Intro: We have been learning about Evaporation and how do Evaporation work. Evaporation when the liquid turns into a gas.

Aim: To evaporate Copper Sulfate (Blue Liquid). To separate the mixture.

Hypothesis: I think there will be some blue stuff that will be left behind the solution.

Equipment: 

1. copper sulfate solution
2. 250ml beaker
3. heatproof mat
4. evaporating basin
5. 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 until it is quarter full.
4. Carefully, place the evaporating basin on the top of the beaker.
5. Turn the element to 8.
6. Heat the solution 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.

Observation: The water started boiling, then the steam heat up the copper sulfate then the copper sulfate evaporated and left with crystals

Conclusion: I can see that my hypothesis is correct because it left with blue crystals on the evaporating dish

Discussion: When the water started boiling because of the element, the steam from the water heats up the evaporating dish where the mixture of solvent and solute are. While heating up the dish, the mixture started evaporating, and it left with crystals in the dish.
