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:
- Add 20mL of sulfuric acid to a 100mL beaker. Heat to 70degrees. Turn off your Bunsen.
- Once heated, use a spatula to add pea-sized portions of copper oxide. Stir for 30secs
- Repeat step 2 until no more dissolved.
- Fold filter paper and place in a funnel. Place the funnel in the second beaker.
- Make sure your first beaker is cool enough to hold and then pour it into the funnel. Gently swirl and allow to filter through.
- Rinse the beaker and fill with 50mL of water and place on a tripod.
- Place evaporating basin on top of the beaker and pour some solution in.
- Gently heat until the solution has reduced by half.
- Take off heat and allow to cool.
Results:
The results from our experiment became a failure why? because there wasnt enough Coppor oxide powder and didnt form any crystals. The solvent (Lquid) of the experiment evaporated from the evaporating basin. The Solute (Solid) there was no solid crystals in the basin. Solution
