scale with widespread environmental effects. Primarily, acid rain is caused by emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) from the combustion of fossil fuels. However, even pure rainwater is slightly acidic (pH of 5.6-6.5) due to the reaction between H2O and dissolved CO2 which produces a weak carbonic acid, H2CO3. 1.2 Issue Acid rain is the result of water droplets in clouds absorbing sulfur dioxide and nitrogen oxides emitted from the surface of the earth as a result of both…

INTRODUCTION Worldwide, air pollution is a growing threat to human health and the natural environment. One of the major effects of air pollution is acid rain and it is caused by sulfur dioxide (SO2) and nitrogen oxides (NOx) gases. The combustion of high sulphur content fossil fuels can release harmful toxic gases into the air and therefore pose serious environmental problems. Coal, oil and natural gas are major energy resources available in environment where as fuel combustion processes and…

Assignment 7 Power Station Emission Aim: The aim of this experiment is to measure the mass of sulphur dioxide in 1m3 of flue gas (waste gas from burning fossil fuels in a power station). To achieve this aim, titration of an unknown solution of sulphuric acid (around 0.2-0.4 mol) and sodium carbonate (0.2 mol) using methyl orange as an indicator. 1. Introduction Fossil fuel is formed from decayed plants and animals that have been converted to crude…

it has on the environment. Chemical Sources In the formation of acid rain, natural and human-made sources are known to play a role. Human activities are the primary contributor of chemical emissions leading to acid rain, mainly nitrogen oxide and sulfur dioxide. Human-made contributors include the burning of fossil fuels by coal-burning power plants, factories and automobiles.…

Roof Discolored? Know Three Potential Reasons Why Nobody wants a roof that is a community eyesore with discoloration. Unfortunately, there may be factors at play that are causing this blemish. In order to fix the problem, you must know what is causing it to occur. Here are three reasons why discoloration can happen to a roof. Pigment From Asphalt Shingles There is a process called extractive bleeding where black pigments found in your roof’s shingles can cause a stain to appear. It typically…

Acid rain is a precipitation which falls from the atmosphere to Earth. It contains a high level of nitrous oxide and sulphur dioxide. When they ge tin contact with water they transform to acid in the atmosphere, and then this acid is carried away by the wind thousaands of miles away from where they were created. The acidity is measured with the potential hydrogen (pH) on a scale from 0-14. The pH scale is a logarythmic measure which means that every change in pH is counted in the amount times…

Acid rain is any form of precipitation that has unusually high acidity (a pH level below 5.6) and caused by the transformation of nitrogen oxides and sulfur dioxide into secondary pollutants. pH is is a scale used that measures the acidity of liquids and ranged from 0 to 14. The lower the number, the higher acidity, or the higher concentration of hydrogen ions. 0-5 is considered acidic and as you move up to 7, this indicates the substance is neutral. The higher numbers on the scale indicate…

Spring Reflection on Pastoral Year Experience Pastoral Reflection: The last 6 months of Pastoral Year has been a great blessing. The people in the Parish received me with such love and care. It will certainly be hard to step away in 3 months time when the Pastoral Year ends. During this Pastoral Year, I have gotten to really know a lot of people in the Parish, some closer than others. A couple that I got to know real well is the Bernard and Rosemarie Scheiff. They treat me like their own son.…

Pollution control equipment such as wet scrubbers control emissions from coal and oil combustion from energy and industrial production bring waste gases in contact with a sorbent that reacts and absorbs the sulfur dioxide. Another option is changing the way power plants burn coal and fossil fuels to reduce the nitrogen oxide created from the combustion. Methods to help mitigate nitrogen oxide emissions from cars is by the use of catalytic converters attached…

Colorado gets about 15.9 inches of rainfall per year. Rain used to be one of the best things that could happen in this state, but as humans pollute our world more and more, rain is becoming harmful. Our precious rainfall is becoming more and more acidic, which is causing harm to plants, wildlife, buildings, and humans. This acidic rain is commonly referred to as acid rain and more properly known as acid deposition. This research will thoroughly examine acid rain, it’s causes, the effects on the…
