evaporate experiment
intro:we have been learning about distillation,evaporation,dilution.
evaporation is when liquid to gas
aim:to evaporate copper sulfate. (sulfur oxygen)- (blue liquid)
hypothesis: i think that it will be disappeared.
equipment:Copper sulfate solution, 250mL Beaker, heat proof 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 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.
Oberservations: the water starts to boil up,and steam is coming out the water
Conclusion: My hypothesis was right leaving the copper sulfate disapear after the water boiled up.
solute=solid
solvent=liquid
solution=mixture
