PREPARATION OF COPPER (II) SULFATE CRYSTALS
|
Diagram showing the Heating of Mixture to Leave a Saturated Solution
|
ACID = Dilute Sulfuric Acid INSOLUBLE BASE = Copper (II) Oxide
|
METHOD:
Add Dilute Sulfuric Acid into a beaker and heat using a bunsen burner flame
Add Copper (II) Oxide (insoluble base) in small amounts and stir until Copper (II) Oxide is in excess (stops disappearing)
Filter mixture into an evaporating basin to remove the excess Copper (II) Oxide
Leave filtrate in a warm place to dry and crystallize
Decant excess solution
Blot crystals dry
|
EQUATION OF REACTION:
Copper (II) Oxide + Dilute Sulfuric Acid → Copper (II) Sulphate + Water
CuO (s) H2SO4 (aq) CuSO4 (s) H2O (l)
