Reaction 15





calcium carbonate + HCl

Chalk (as shown above) and limestone are made primarily of calcium carbonate. All acids react with calcium carbonate in the same way, including the acid in acid rain. The long term results of acid rain on sculptures and other objects made of limestone can be devastating. This headstone in London has been severely damaged.

    a. Complete and balance the reaction.
    b. Classify the reaction.
    c. What is the gas that is formed?
    d. What would be the common source of acid coming in contact with the sculpture?
    e. Calcium carbonate is not the only chemical that would react this way. Name two others.
