> Mass aluminum. Fold in ½ & coil loosely.

> Place in beaker and let sit overnight.

Day 2

  • Pull out Aluminum and rinse into beaker
  • Mass filter paper, put name on it
  • Put paper in funnel and funnel into the Erlenmeyer flas.
  • Pour in mixture. Rinse beaker three times.
  • Rinse funnel and paper twice.
  • Remove Paper and let dry overnight.

Day 3

  • Mass filter paper
