Evaporation

Aim:
Aim: To seperate a solute from a solvent in a solution using evaporation.

Equipment:
- Copper sulfate Solution
- 250 mL beaker
- Heatproof mat 
- Evaporating basin
- Bunsen burner
- Tripod
- Gauze mat

Method:
1.  Set up the bunsen burner, tripod and gauze mat. Don't place the bunsen burner under the tripod yet.
2. Add approximately 50 mL of how water to your beaker and place it on top of the tripod, on the gauze mat.
3. Add enough copper sulfate solution to quarter fill the evaporating basin.
4. Carefully place the evaporating basin on top of the beaker.
5. Light your bunsen burner. Open the air hole and gentle push the bunsen burner under the tripod.
6. Heat the solution until most of the solvent has been evaporated and crystals  of solute are forming.
7. Turn off your bunsen burner.

Results:

All of the solvent is evaporated and all that is left is the solute.

Discussion:

After the evaporation of the solution and all of the solvent evaporated all of that's left is the solute which is the blue crystals.
