Competition between metals Sarah Belanger Competition between metals 1) Purpose: To obtain an order of reactivity of metals by investigating displacement reactions. 2) Hypothesis: If a metal that is higher in the reactivity series displaces a metal lower in the reactivity series, then copper will be the least reactive because it is lower in the reactivity series than the other metals. 3) Safety Precautions: Lead (II) nitrate solution is poisonous. Wash your hands at the end of the experiment. 4) Procedure: Clean each metal with sand paper, and then add each metal to a solution. Leave the test-tube for 3 min and then scrape out each of the tubes. 5) Observations: Magnesium sulphate Lead (II) nitrate Copper (II) sulphate Iron (II) sulphate Zinc sulphate Magnesium + + + + Lead - + - - Copper - - - - Iron - + + - Zinc - + + + + = a reaction...
