Crest bronze award: Monitoring acid rain
In this Crest Award accredited project, students monitor levels of atmospheric sulfur dioxide and rainfall acidity in the school grounds. Suggested investigations include:
- Investigate various methods of measuring acidities between pH4 and pH7, to decide which method is most accurate.
- Compare the effects of dissolving carbon dioxide (CO2), sulfur dioxide (SO2), and nitrogen dioxide (NO2) in water.
- Investigate how the pH values of sulfuric acid and nitric acid change as they become more dilute.
- Find out how to distinguish between sulfuric(VI) acid and nitric(V) acid.
- Find out how sulfur dioxide levels are monitored. Design a method for measuring atmospheric sulfur dioxide in the school grounds.
