Physical Properties of Copper

• Everyday methods of identifying copper from a
  laymans perspective
• Copper has certain unique physical qualities
• Can be tested without little to no scientific
  equipment

Color of Copper

• Easiest and the most effective technique for
  identifying pure copper
• Clean your copper item with a mixture of table
  salt and vinegar
• If the color that comes out after cleaning
  shinning reddish brown, it is pure copper
• During cleaning, Hydrochloric acid cleans up the
  top surface of your copper item, exposing
  original copper from underneath.

Copper Density

• Test whether the density of your copper item
  matches with that of pure copper
• Density of pure copper 8.96 grams per cubic
  metre
• Use an electronic weighing device to measure the
  exact weight of copper item
• Measure the dimensions of your copper item and
  calculate its volume
• Results closer to 8.96 signify purity of copper

Electrical and Magnetic Properties of Copper

• More reliable and technical ways of testing the
  quality of copper
• Two key chemical properties for easy testing are
  Conductivity and Magnetism

Resistivity and Conductivity

• Two of the most reliable electrical properties of
  any element
• Weight, and hence density, can vary at different
  places, but electrical properties dont
• Copper has a resistivity of around 1.7 x 10-8
  ohm-mtrs at room temperature
• Calculate resistivity of copper item using
  ohmmeter to determine purity

Magnetism

• Copper is negligibly magnetic
• Impurities mixed with copper items make them
  magnetic
• Bring a magnet closer to the copper item you wish
  to test
• Pure copper will show no sign of influence under
  a magnetic force
