Document Summary
After completing this section, you will be able to: recognize the chemical reactions that cause acid rain, list the effects of acid rain, explain the suggested control strategies. Use the glossary (top menu bar) to check out these terms: fossil fuels. How does acid rain happen: acid rain. When atmospheric carbon dioxide dissolves in water it forms carbonic acid. The acid formed dissociates partially generating small amounts of hydrogen ions. The hydrogen ions formed are responsible for the weakly acidic nature of rain. The acidity (a measure of hydrogen ion concentration) of a solution is conveniently described in terms of ph scale. According to this scale, if: ph < 7: solution is acidic ph > 7: solution is basic ph = 7: solution is neutral. For example lemon juice is acidic. ph laboratory. This virtual laboratory provides a visual example of how different substances can effect the ph balance.
