aim : to evaporate copper sulfate ( blue liquid) to separate the mixture
hypothesis : I think that the colour is going to change.
equipment : copper sulfate solution , 25ml 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 its quarter full
4. carefully , place the evaporating basin on top of the beaker
5. turn on the element to 8
6. heat the solution until most of the solvent has been evaporated and crystals of solute are forming
7. turn off the element
