What is acid rain? Rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm‚ typically to forests and lakes. What chemicals make rain acidic‚ and how does it happen? Besides water‚ and carbonic acid (from carbon dioxide dissolved in the rain droplets)‚ the primary components of acid rain are sulfuric acid‚ which comes from sulfur dioxide derived from the burning of coal‚ and nitric acid‚ which from nitrogen emissions. Where do these chemical come from?

The purpose of this experiment was to study the effect acid rain has on seed germination and after performing this experiment is can be concluded that acid rain has a negative effect on seed germination. When seeds are soaked in an acidic solution the process of germination slows. Acidic solutions‚ while do slow growth of a seed‚ they do not kill the seed. A seed can be dormant for a majority of its lifespan‚ seeds watered with acid solutions stayed in a dormant condition. For example‚ trial three

Effects of Acid Rain Background Information Acid rain is when there is a mix of wet and dry deposited material in the atmosphere that have higher levels of nitric and sulfuring acid. These chemicals formed can be from natural causes‚ like volcanoes and the decay of vegetation‚ or man made causes like fossil fuel combustion. Acid rain can be measured using the pH scale‚ and will always be on the lower end of the spectrum because of its acidity. Water has a pH of 7‚ but the acidity of normal rain tends

Acid Rain Lab #1 Chem. 1 20 February 2016 Concordia University Texas Angelina Luna angelinaluna97@yahoo.com Chem 1- Sect C Acid Rain Lab #1 Professor Koeck Abstract In this experiment our main objective was to create three gaseous oxides CO₂‚ SO₂ and NO₂ by using data that was collected using a pH sensor which was connected to a laptop with LoggerPro and Vernier. We created the gases by bubbling each gas into the water to create the three acidic solutions we were looking for. Once that

Global Warming and Acid Rain INTRODUCTION The phrase Global Warming has become familiar to many people as one of the important environmental issues of our day. Many views have been expressed concerning it‚ from the doom-laden to the dismissive. There is little debate that the earth is undoubtedly warming. It has been the subject of intense debate for decades now. Greenhouse gases such as carbon dioxide and industrial gases from fossil fuels play a huge role in why our environment is changing

Acid Rain Lab Report Introduction: The problem was to see how crushed chalk and whole chalk weather differently. The independent variables are The temperature of the liquids The surface area of the chalk‚ crushed vs whole The dependant variable was the weathering of the chalk; this was calculated by measuring the foam reactant. Procedure: Part B- For the two partners recording data with the room temperature liquids‚ the materials where collected first. Two of the graduated

Acid Rain Introduction: Titrations are often recorded on graphs called titration curves‚ which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the two solutions). The equivalence point on the graph is where all of the starting solution (usually an acid) has been neutralized by the titrant (usually a base). One can easily find the pKa of the monoprotic acid by finding

“Acid Rain” Environmental science What is Acid Rain? Acid rain is a rain or any other form of precipitation like rain‚ fog‚ snow‚ or hail that contains harmful substances higher than normal amounts of such as nitrogen and sulfur oxides‚ that is unusually acidic‚ meaning that it possesses elevated levels of hydrogen ions (low pH). Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. The acid deposition is occurs

Acid Rain Acid rain‚ or acid desposition‚ is simply common rainfall that has been polluted sufficiently by atmospheric pollution. Acid rain contains two types of acids: nitric and sulfuric. These chemicals‚ or precursors‚ are emited by natural sources such as volcanoes and decaying vegetation. Man-made sources are also primary causes for emissions of sulfur dioxide and nitrogen oxides that come from fossil fuel combustion. The most common emiters of these fossil fuels are power plants‚ factories
