We have tried filtering to get a solid out of a liquid but this time we can't see the solid because it is dissolved in the liquid. If we heat up the solution then the solvent will evaporate off and we will be left with the solute.
AIM - To use evaporation to separate a solution into a solvent and solute.
HYPOTHESIS - I think that the water will evaporate and that the copper sulfate will be left in the bottom of the beaker in a cluggy state.
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 it 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.
COPPER SULFATE SOLUTION -
Solvent - Water
Solute - Copper sulfate
