pH and Acid RainpH and Acid Rain

• Draw a picture of the pH scale and include an example of an item that would exist at each part of the scale.

• Use red to indicate acid, blue for base, and brown for neutral.

• Draw a diagram of how acid rain forms, make sure you label and include details of its formation.

• Include a description of sources of acid rain that include both manmade sources and natural sources.

• Describe the effects of acid precipitation on:

aquatic life and vegetation Humans and stone and metals.

• List 3 solutions that can be implemented to help prevent acid precipitation.
