The burning of fossil fuels such as coal, heating oil and gasoline releases chemicals into the atmosphere. These chemicals combine with water vapor in the air to form acid rain that harms the environment.
•
The effect of acid rain on a lake may be reduced through natural buffers present in some materials on the bottom of the lake. Buffers are chemicals that act to keep the pH of a solution relatively constant. In this activity, you will determine which type of lake bottom material (sand or limestone) is best for buffering the effects of acid rain.
