Making Salts ll

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

Equipment - Copper oxide powder, dilute (o.5 mol L-1) sulfuric acid, 50 mL measuring cylinder, two 100 mL beakers, Bunsen burner, tripod, gauze mat, funnel, filter, paper, thermometer, spatula, evaporating basin, stirring rid.

Method: 

1. Add 20 mL of sulfuric acid to a 100 mL beaker. Heat the acid until it reaches 70.C. Turn off your Bunsen Burner.
2. Once it is heated, use a spatula to add pea-sized portions of copper oxide to the beaker. Stir the mixture for 30 seconds.
3. Repeat sep 2 until no more will dissolve. Allow the beaker to cool.
4. Fold the filter paper and place it in the funnel. Place the funnel into the second beaker. 
5. Make sure the beaker is cool enough to hold at the top. The contents should still 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 paper in the funnel. Allow to filter through.
7. Rinse the beaker you used to heat the mixture previously, and place it back on top of your tripod 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 evaporating 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 i has cooled down, move the evaporating basin to a warm place where it will not be disturbed 

Result:

This is what ended up with.....

Conclusion - This experiment was a success and we got the correct results that we were looking for. Next time we do this experiment, we will not add to much water because it will not turn crystal for a bit, but overall this was a fun and success experiment.
