Separating a Mixture using Evaporation

 Separating a Mixture using Evaporation:

Aim:

Hypothesis: they will crystalize

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 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 - careful not to touch as will be hot for a long time.

Observations:

We started off by putting the beaker on the element, with the evaporating basin that had Copper sulfate solution inside. It took time for the water to start boiling but once it did, it had a nasty smell to it. Steam started coming out so we turned off the element and let it sit.

The solution started crystalizing.
