   • 2. Fold two filter papers into a conical shape. Place each filter into a funnel.
     • 3. Label your beakers as beaker 1 calcium carbonate and beaker 2 copper sulfate, label your Erlenmeyer flasks the same way.
       • 4. Collect one spoonful of copper sulfate and place it in 40 mL of water in a beaker number 2. Repeat for calcium carbonate in beaker number 1. Stir.
         • 5. Read the steps 1 and 2 before you pour it into the filter paper.
           • 6. Note the time taken for each filter, how clear the filtrate is, and if there is any residue in the table.
