Separation methods: filtration

1. Place a funnel in each Erienmeyer flask

   • Fold two filter papers into a conical shape. Place each filter into a funnel.
     • Label your beakers as beaker 1 calcium carbonate and beaker 2 copper sulfate, label your Erlenmeyerflasks the same way.
       • Collect one spoonful of copper sulfate and place it in 40 mL of water in a beaker number 2.Repeat for calciumcarbonate in beakernumber 1. Stir.
         • Pour the stirred contents of beaker 1 –calcium carbonateinto the conical filter paper.Start the timer as soon as you begin to pour. Keep adding the mixture tothe beakeruntil allthe liquid has been filtered. Stop the timer when the filter stops filtering.Leave any remaining sediment in the beaker. Record the time in thetable.
           • Pour the stirred contents of beaker 2 –copper sulfateinto the conical filter paper. Start the timer as soon as you begin to pour. Keep adding the mixture tothe beaker until allthe liquid has been filtered. Stop the timer when the filter stops filtering. Leave any remaining sediment in the beaker. Record the time in the table.
             • Note the time taken for each filter, how clear the filtrate is,and if there is any residue in the table!
