Worksheet: Reactivity Series

In this worksheet, we will practice using the reactivity series to describe reactions of metals with water, acids, oxygen, hydrogen, and metal oxides.


When powdered metal A is mixed with an aqueous solution containing ions of metal B , a precipitate of metal B is formed. Based on this observation, what may be concluded about the relative reactivities of metals A and B ?

  • AIt is not possible to determine the relative reactivities of the two metals.
  • BMetals A and B are equally reactive.
  • CMetal A is more reactive than metal B .
  • DMetal A is less reactive than metal B .


It is often necessary to paint or galvanize iron objects to protect them from corrosion. Aluminum, however, resists corrosion without the need for a protective coating. Why is the corrosion resistance of aluminum greater than that of iron?

  • AAluminum is less reactive than oxygen so does not corrode in the presence of air.
  • BAluminum is less reactive than iron so is corroded more slowly by oxygen in the air.
  • CAluminum reacts with nitrogen in the air to form a protective layer of aluminum nitride.
  • DWater in the air binds to aluminum to form a protective layer.
  • EAluminum reacts with oxygen in the air to form a protective layer of aluminum oxide.
