aim: To produce copper sulfate salt by reacting copper oxide with an acid.
equipment: Copper oxide powder,dilute,sulfuric acid,cylinder,beakers,bunsen burner,tripod,gauze mat,funnel,filter paper,thermometer,spatula,evaporating basin,stirring rod.
method:
- Add 20 ml of sulfuric acid to a 100ml beaker. heat the acid until it reaches 70'c. Turn off your bunsen burner.
- Once heated, use a spatula to ass pea-sized portions of copper oxide to the beaker. Stir the mixture for 30 seconds.
- Repeat step 2 until no more will dissolve. Allow the beaker to cool.
- Fold the filter paper and place it in the funnel. Place the filter funnel into the second beaker.
- Make sure the beaker is cool enough to hope at the top. The contents should still be hot. You may need your teacher to complete this step.
- Gently swirl the contents of the beaker to mix, and then pour into the filter paper in the funnel. Allow to filter through.
- Rinse the beaker you used to heat the mixture previously, and place it back on top of your tripod filled with 50-60 ml of water.
- Place the evaporating basin on top of the beaker and carefully pour some of the solution from the beaker into the evaporating basin.
- Gently heat the beaker until the solution in the evaporating basin has reduced by half.
