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.
If environmental scientists monitoring pollution levels are measuring buffer levels in two specific
lakes, and 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.
