Question 1

Describe a method for making pure copper sulfate crystals from copper carbonate and dilute sulfuric acid. Name all the apparatus used

Answer 1

• Place 25cm³ of dilute Sulfuric acid in a beaker
• Using a spatula, place in Copper Carbonate one
  spoon at a time, stirring until it is in excess
  (when no more gas is being given off)
• Using filter paper and a funnel, filter off the excess
  calcium carbonate
• Heat off half of the remaining volume of Copper
  Sulfate in an evaporating dish
• Finally, leave the solution to crystalise, producing
  pure Copper Sulfate crystals
