Crystallization

Crystallization

1. 1. Weigh 28 g of the copper sulfate in the beaker.

   • 2. Prepare a hot concentrated solution of the copper sulfate by pouring 20 ml of hot water into the beaker. Stir the solution until no more solid will dissolve.
     • 3. Pour the blue copper sulfate solution through the filter paper into the beaker. The undissolved copper sulfate will remain on the paper.
       • 4. Quickly pour the solution into the test tube.
         • 5. Tie the string to the wood stick. Attach the paperclip to the end of the string and arrange it as shown.
           • 6. Leave to cool overnight in the test-tube rack.
             • 7. The next day you must come to the lab to take a picture of what happened and to take notes of the changes that have taken place in the test tube.
