In doing this they studied how the water in these water sheds were sulfuric and how rains became acidic rains.In 1979 the amounts of sulfuric acid began to die down because of the Clean Air Act....[tags: Acid Rain Chemical Reactions Essays] - Acid Rain Acid rain has become an environmental concern of global importance within the last decade.
[tags: Carbon dioxide, Fossil fuel, Acid, Acid rain] - The Effects of Acid Rain on Statues Introduction ------------ During this investigation, I will use dilute hydrochloric acid as the acid rain and crushed calcium carbonate as the chemical of the statues.
Then I will time how long it takes for the limestone powder to react until there is no more left when the acid is added to it.
They found that haze pollution would be reduced by between 11–17% if there was a 50% reduction in ammonia with improved agricultural management and a 15% reduction in sulfur dioxide and nitrogen oxides.
However, the model also revealed that the reduced levels of ammonia could reduce the p H of rain by up to one unit.
Grade Level: 5 (4-6) Time Required: 45 minutes Expendable Cost/Group: US $2.00 Group Size: 4 Activity Dependency: None Subject Areas: Chemistry, Earth and Space, Physical Science, Science and Technology is the estimated cost of supplies needed for each group of students involved in the activity.
Any reusable equipment that is necessary to teach the activity is not included in this estimate; see the Materials List/Supplies for details.
The team concluded that while it was possible to reduce ammonia emissions significantly, any economic benefit of the plans would be partially offset by the increased frequency of more acidic rain.
Instead, the researchers suggested that a better approach would be a region-specific strategy that examines multipollutant controls to prioritise the needs of different areas in the country.
China’s plans to cut ammonia emissions to reduce haze pollution may worsen the country’s acid rain problem, a new study has found.
To evaluate the potential impact of the government’s plans to reduce ammonia in the atmosphere, a team of researchers in China used models to predict how these cuts would affect haze pollution and acid rain.
