Making salts II

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

Method: Add 20 mL of sufuric acid to a 100 mL beaker. Heat the acid until it reaches 70 Degrees Celsius. Then turn off your bunsen burner. , Once heated, use a spatula to add 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 hold 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. , Leave the evaporating basin to cool. Once cool, move the evaporating basin to a warm place where it will not be disturbed (i.e. a window-sill) and observe over the next few days. Blue copper sulfate crystals should form.

Results: I saw that my group did pretty well because there was n liquid left in our evaporating basin, it was great crystallisation.

Discussion: Copper oxide + Sulfuric acid = Water + Copper Sulfate, The Acid and the Oxide made water and the Copper and the Sulfuric made Copper Sulfate.

Conclusion: I think my group was successful in this experiment I wouldn't change anything about the outcome.
