Making a Copper Sulfate Salt

MAKING A COPPER SULFATE SALT

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

Equipment: Copper oxide powder, dilute sulfuric acid, measuring cylinder, 2x 100mL beakers, bunsen burner, tripod, gauze mat, funnel, filter paper, thermometer, spatula, evaporating basin, stirring rod.

Method:

1. Add 20mL of sulfuric acid to a 100mL beaker. Heat to 70degrees. Turn off your bunsen.
2. Once heated, use a spatula to add pea-sized portions of copper oxide. Stir for 30secs
3. Repeat step 2 until no more dissolved.
4. Fold filter paper and place in the funnel. Place the funnel in the second beaker.
5. Make sure your first beaker is cool enough to hold and then pour it into the funnel. Gently swirl and allow to filter through.
6. Rinse the beaker and fill with 50mL of water and place on a tripod. 
7. Place evaporating basin on top of the beaker and pour some solution in.
8. Gently heat until the solution has reduced by half.
9. Take off heat and allow to cool.

Results: The results of our experiment was a failure because not that much crystal formed and there is only a bit of crystal. (solvent) liquid evaporated and did not form crystals.
