In this experiment the aim was to get Copper Carbonate to react with Sulphuric Acid to get Copper Sulphate.
5 Grams of Carbon Carbonate
Weighing Boat, Spatula & Scales
25 cm³ Sulphuric Acid
Tripod and Gauze
Bunsen burner, Splint and Matches
Filter Funnel and Filter Paper
Sulphuric Acid – Corrosive
Safety Glasses and Lab Coats to be worn
Any Spillage, dilute with water and clear IMMEDIATELY
Weigh out approximately 5 grams of Copper Carbonate into a weighing boat. o
Measure out 25 cm³ of dilute Sulphuric Acid into a beaker and using a Bunsen burner heat on a tripod and gauze until it JUST starts to boil. Turn the Bunsen burner off. o
Add 1 spatula of Copper Carbonate to the Sulphuric Acid and leave it to react, this will give a clear blue solution. Keep adding further portions of Copper Carbonate, do this until there is no more effervescence (Fizzing/Bubbling). o
Pour the contents of the beaker into a filter funnel that has been lined with filter paper; rest this on top of a conical flask. o
Once the solution has finished filtering through, pour the liquid from the conical flask into the glass dish and leave to stand for a week.
AFTER A WEEK.
Use suction filtration to separate the crystals from any remaining liquid. o
Examine the crystals using a magnifying glass. Sketch the shape of the crystals if you are able to see them clearly.
SUMMARY OF RESULTS:
After a week the results were very evident. In the glass dish there were large deposits of vivid blue crystals that were irregular in shape; this occurrence was due to the solution cooling rapidly, probably because the dish was very close to the window and the weather was warm on the day that the experiment was carried out. These blue crystals were Copper Sulphate.
