collecting it in the beaker. A wash bottle may also be useful - using a stream of water to remove the
copper from the zinc may help. Remove the zinc from the solution using forceps, and place it in the
labeled waste container in the hood.
9. Set up a filtration apparatus, with a 250 mL beaker to collect the filtrate.
Record the mass of a dry
piece of filter paper before folding it and placing in your funnel.
10.
Filter the copper metal out of the solution and into the filter paper.
After filtering, your teacher will
remove the filter paper from the funnel, and place it into the 100 mL beaker.
Discard the filtrate in
the 250 mL beaker down the sink with running water.
11.
Place your 100 mL beaker/filter paper in the area designated by your instructor.
The filter paper will
dry overnight.
Day Three
–
Massing the dried copper.
12. Obtain your 100 mL beaker with the dried filter paper.
Without removing the filter paper
, mass
the beaker and contents. Record this mass (clearly labeled) in your lab book. Dispose of your filter
paper and copper in the labeled waste container provided. Clean your beaker, and return it to your
instructor.
Data Table and Observations:
Create an appropriate data table for this lab.
You may choose to make 3 separate data tables, one
for each day.
Make sure that your entries are clearly labeled.
Below the data table(s), make a he
ading of “Observations.”
You will be recording a lot of
