Environmental scientists can use a similar lab kit to test collected water samples from
bodies of water. In lakes and streams, calcium carbonate (CaCO3) causes alkalinity,
which allows it to function as a buffer, neutralizing any acid rain that may enter the
water supply. A buffer is a substance that serves to resist small changes in acidity or
alkalinity in a solution.
Environmental scientists monitoring pollution levels are measuring buffer levels in
two specific lakes. They found that Lake B had a greater ppm of calcium carbonate
than Lake A.
Which of the two lakes would be able to neutralize a greater amount of acid rain?
Explain your answer.
