Mining for Metals
2
Background Information

• Mining for minerals has been taking place for
  hundreds of years.
• These minerals are mined to obtain pure metal
  samples.
• Some metals are easier to extract than others due
  to their reactivity.

3
The Situation

• You have been recruited with your lab partner to
  determine the ease in which several metals will
  be extracted from an ore.
• The following metals are to be tested Al, Cu,
  Mg, Na, Li, and Pb.
• You have the following chemicals available for
  testing distilled H2O, 0.1 M HCl, 1.0 M HCl, 3.0
  M HCl.

The Assignment Part 1

• You are to create and perform an experiment to
  test the reactivity of these metals.
• Your experiment needs to be designed such that
  your results can be reproduced by any pair of lab
  partners in your class.
• Your experimental design must be approved by your
  teacher before you can conduct the experiment.

5
The Assignment Part 2

• After completing your experiment, you need to
  work with your lab partner to analyze your data.
• If necessary, repeat any part of your experiment
  to verify results.
• Form your conclusions.

6
The Report

• What should be reported?
• - You and your lab partners name
• - Your experimental design
• - Your data
• - Your analysis of the data
• - Your conclusions
• (i.e. which metal is the easiest to extract ?
  which metal is the hardest to extract)
