Making 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 a 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 & Discussion : 

When we put the powder in the solvent the solute turned into a black solution. Then we filtered the solution into another clean beaker. When we were filtering the solution the dark black liquid turned into a light blue solution. Then we put the liquid in an evaporating basin. We left the blue solution overnight. The next day crystals formed.

Conclusion:
The experiment involved turning solids into liquids and creating a solution. Our crystals were all different sizes. We had a lot of equipment to use. The final product turned out well
