Salt crystals

 Aim: To produce copper sulfate salt by reacting copper oxide with an acid.

Method: 

1.  Add 20 ml of sulfuric acid to a 100 ml beaker. Heat the acid until it reaches 70 degrees Celsius. Turn off your Bunsen burner.

2. Once heated, use a spatula to add pea-sized portions of copper oxide to the beaker. Stir the mixture for thirty seconds.

3. repeat step two until no more will dissolve. Allow the beaker to cool.

4. Fold the filter paper and place it in the funnel. Place the filter funnel into the second beaker.

5. Make sure the beaker is cool enough to hold at the top. The contents should be hot. You may need your teacher to complete this step.

6. Gently swirl the contents of the beaker to mix, and then pour into the filter paper in the funnel. Allow the filter through.

7. Rinse the beaker you used to the heat the mixture previously, and place it back on top of your tripod filled with 50-60 ml of water.

8. Place the evaporating basin on top of the beaker and carefully pour some of the solution from the beaker into the evaporation basin.

9. Gently heat the beaker until the solution in the evaporating basin has reduced by half.

10. Leave the evaporating basin to cool. Once cool, move the evaporating basin to a warm place where it will be not disturbed (i.e. a window-sill) and observe over the next few days. Blue copper sulfate crystals should form.

Results:

Discussion: When adding copper oxide to the water it turned black until we filtrated the mixture it came out blue on the other side.

Conclusion: Due to the fact that we added a little too much of the substances i thought it would have turned out a bit messed up but really it turned amazing.
