has a pH of 5.0 or less. Most acid deposition ranges from pH 4.3 to 5.0. While a small portion of the Sulfur dioxide and Nitrogen oxide that cause acid rain is from natural sources such as volcanoes, most of it comes from the burning of fossil fuels.  The major sources of Sulfur dioxide and Nitrogen oxide in the atmosphere are: Burning of fossil fuels to generate electricity.  Two thirds of Sulfur dioxide and one fourth of Nitrogen oxide in the atmosphere come from electric power generators, vehicles

to explore the development of preventative measures designed to reduce and avert acid rain across the globe. Environmental effects of Acid Rain and causes Acid rain causes long term damage to environmental habitats such as forests and lakes. When sulfur dioxide and nitrogen dioxide are released into the atmosphere they react with atmospheric molecules, sulfuric and nitric acid are formed; the equations on the slide show the reactions that occur between the compounds and HO molecules in the air. These

Acid Rain Acid Rain is a common term to describe how acid falls from the atmosphere onto the earth. The real term is acid deposition; this term refers to acidic rain, fog, and snow. Acid Rain occurs when the two gases sulfur dioxide (SO2) and nitrogen oxides (NOx) react with each other in the atmosphere with water, oxygen, and more chemicals to form many acidic compounds. Scientists measure acid rain by using a scale called a pH scale. What they do is measure the normal rain. Normal rain is slightly

create electricity pollutants such as sulfur dioxide and nitrogen oxides are released into the air. They then mix with oxygen and water in the air to form acid rain. These chemicals can travel long distances in the rain before being deposited. (Epa.gov) There are several different pollutants that can lead to acid rain such as SO2, SO3, NO2, and CO2. These pollutants react with water to create acids as shown below. Sulfur dioxide + water  sulfurous acid Sulfur trioxide + water  sulfuric acid Nitrogen

used. First of all, “What is acid rain?” Basically acid rain is rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm, typically to forests and lakes. Acid rain is caused by a chemical reaction that begins when sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere. The main cause of acid rain is the burning of fossil fuels by coal-burning power plants, factories, and automobiles. These substances can rise very high into the atmosphere

rain’ refers to the atmospheric deposition of acidic constituents that impact the earth as rain, snow, particulates, gases, and vapor. The bulk of the acidity in rain comes from the reaction of sulfur dioxide (SO2) with hydrogen peroxide in clouds, a reaction that produces sulfuric acid. Even though sulfur dioxide and carbon dioxide occur in the air naturally, burning fossil fuels adds more of these chemicals into to the air. When these pollutants are released into the air, they mix and react with

The world we live in today has become a nest for pollution, toxic waste and environmental deterioration. In order to improve our planet, acid rain is a main factor to be considered and must be controlled before the damage worsens. In order to understand what acid rain is, we must first understand the term “acidity”. Acidic is a way to describe chemical compounds and it is measured on the pH scale, a logarithmic measure of the concentration of hydrogen ions (H+) in precipitation (1). This scale

done in a semi-solid medium known as a SIM test. SIM stands for Sulfur-Indole Motility. So, in this test, I am able to find out three different characteristics in one test. For this test, you merely swipe the top of the surface and then stab the medium with your inoculating tube. Then the medium is then incubated at 37°C for 48 hours. After it has been incubated, you are able to tell the results. The first part of this test is the sulfur test. The medium contains cysteine, an amino acid, and iron.

Acid Rain: Effects on Living Organisms In latest days, the water in our atmosphere has indication that it is already polluted with nitrogen dioxide and sulfur dioxide, both are chemical compounds that develop acid once joint with water. When the water vapor compresses and falls down to the land, it is usually denoted as acid rain, though acid rain likewise falls down as snow or as dried out small particles, blending with water once it touches surfaces on the land. Acid rain lead to numerous upsetting

(Andrei, 2012) Sulfur dioxide (SO2) is a group of highly reactive gasses that is mainly produced from emissions caused by fossil combustions, mainly smelting. (Dowdey, 2011) Smelting is a process used to separate a metal from the ore to high temperatures. The gas phase sulfur dioxide becomes oxidized by reaction with the hydroxyl, yields an intermolecular reaction, ultimately forming sulfuric
