Acid Rain Essay -- Geology

ACID RAIN - DEFINITION Scientists have sight that air pollution from the burning of fossil fuels is the major cause of deadly rain down. The main chemicals in air pollution that create caustic rain are sulfur dioxide (SO2) and nitrogen oxides (NOx). Acid rain usually forms laid-back in the clouds where sulfur dioxide and nitrogen oxides react with water, oxygen, and oxidants. This mixture forms a flaccid solution of sulfuric acid and nitric acid. Sunlight increases the rate of whatsoever of these reactions. Rainwater, snow, fog, and other forms of precipitation containing those mild solutions of sulfuric and nitric acids fall to priming as acid rain. Acidity is measured using a pH scale, with the number 7 being neutral. Consequently, a substance with a pH machinee for of less than 7 is acidic, while one of a value greater than 7 is basic. Generally, the pH of 5.6 has been used as the baseline in identifying acid rain, although there has been much debate over the acceptance of this value. interestingly enough, a pH of 5.6 is the pH value of carbon dioxide in correspondence with distilled water. That means, acid ran is defined as any rainfall that has an acidity direct beyond what is expected in non-polluted rainfall. Any precipitation that has a pH value of less than 5.6 is considered to be acid precipitation. The tercet main sources of acid deposition are 1. Coal in electricity 2. Base alloy smelting 3. Fuel com moundtion in vehicles This is a small diagram that shows where some of the pollution comes from and where it goes to when it turns into acid rain.... ...e EcoLogo. They minimize the use of environmentally hazardous substances and maximise energy efficiency and the use of recycled materials. Buy locally produced or full-grown items from local stores and businesses. They dont re quire the transportation energy of import products.Transportation Walk, ride your bike or take a bus to work. Share a ride with a friend or co-worker. remove your engine tuned at least once every six months. run across your car tire pressure regularly. Use alternative fuels, such as ethanol, propane or natural gas. Avoid unnecessary idling. In the winter, warm your cars engine with a block heater for two to three hours prior to driving, rather than plugging in the battery overnight. Reduce the number of trips you fox in your car. Drive at moderate speeds. Take the train or bus on long trips. Go CFC-Free.
