Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic. Pollution is the cause of all acid deposition.
What causes ‘acid rain’?
Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground. Examples of what might cause this reactions are:
- Cars and their exhaust.
- The usage and burning of fuel and oil.
- Factories and refineries that burn fuel, oil, and coal.
How does acid rain affect plants growth?
The process that is the center of our activity is how acid rain affects the growing of the plants. We are very interested on how this can differentiate from normal rain. We are very curious on seeing how plants are being affected by acid rain rather than by normal. What we are trying to find or determine in our investigation is the danger this can cause to fauna and flora. Acid Rain is produced by a reaction that begins when compounds like sulfur and nitrogen and they are released into the air. In order to recreate acid rain, we will mix lemon juice and water in order and see how it affects plants. We will record data as the plants grow.
We believe that if we increase the acidity of water with lemon, the rate of the plants’ growth will decrease. We believe that for each 1 pH increase in the acid solution the plants will grow less than normal. We believe all plants will survive.
