Given that the most common mineral in limestone is calcium carbonate, describe how limestone objects are corroded by the sulfuric acid in polluted air. What chemical reaction is involved here? Sulfuric acid formation in the air emanates from pollutants released in the atmosphere especially, from manufacturing industries (Hewayde, Nehdi, Allouche & Nakhla, 2007). When the gas, (sulfur dioxide) is released into the air, it combines with oxygen to form another gas (sulfur trioxide, SO3), which reacts with water to form sulfuric acid (Revie, Uhlig & Wiley, 2011). The reaction is indicated below;
S (s) +O2 (g) SO2 (g)
SO2 (g) + O2 (g) SO3 (g)
SO3 (g) + H2O (l) H2SO4 (aq) (Hewayde et al., 2007) Sulfur dioxide results when a reaction occurs between the sulfur element and oxygen in the air. The acid occurs in the air in the form of Sulfuric acid mists responsible for the corrosion of various metallic and limestone-rich objects. Usually, acid rain results when air containing traces of sulfur dioxide mixes with water (Revie et al., 2011). The acid rain, owing to its PH leads to the corrosion of monuments statues plus memorial, whose main component is calcium carbonate CaCO3. The chief source of sulfur dioxide, in United States, is from electric power plants (Hewayde et al., 2007). The rest comes from industrial sources, combustion of fuels, automobiles and other sources. Acid mists responsible for the corrosion of objects can occur in the air when the humidity of the air is
c) Silver jewellery tarnishing in the air is a chemical property because the silver is reacting with the air, changing the silver
Water is the key element that erodes through the layers of rock in cliffs. Water vapour reacts with gases in the air, such as sulphur dioxide (SO¬¬2) and nitrogen dioxide (NO2), to form sulphuric acid (H2SO4) and nitric acid (HNO3), both of which are components of acid rain. The weak acids will in turn react with limestone which contains calcium
This is due to the ejection of approximately 200 million tons of sulfur dioxide into the atmosphere (Ethridge, 2005). This mammoth quantity of substance can cover Britain knee-high (Tillotson, 2016). Sulfur dioxide is a reflective aerosol; this means it reflects incoming radiation (.
The main sources of pollution caused by this process are process wastes and emissions of contaminated air. Acid rain is one of the emissions that contributes to pollution. The process of smelting sulphide ores produces sulphur dioxide gas; this chemical reacts in the atmosphere to form a mist, which then falls to earth as acid rain. To reduce this effect, new technology has been created and plays an important role in reducing smelting related pollution. Previously, old smelting machines were the cause of most of the sulphur dioxide generators. Using machines such as electrostatic precipitators, almost all of the sulphur is captured prior to the emission and returned to the
Examples of greenhouse gases include carbon derivatives such as carbon dioxide (CO2) and monoxide gases (CO). According to Collins, other greenhouse gases are the derivatives of sulfur which include sulfur dioxide(SO4) and sulfur monoxide (SO2) (36). Collin’s work is relevant to the discourse since it focuses on hurricanes in reference to climate change. Given his knowledge on the topic, his knowledge on the occurrence of hurricanes cannot be overlooked. As Collins notes, these gases come from increased human activities which lead to the consumption of fossil fuels. For instance, the burning of fossil fuels such as coal and petroleum leads to the production of carbon monoxide and dioxide. Mostly, these gases are released from industrial and commercial activities. On the other hand, the gas derivatives of sulfur are often released from activities such as the use of fertilizers. In all these cases, their concentration in the earth’s atmosphere is
The sulfur cycle has two processes, atmospheric and terrestrial. The terrestrial process deals with the weathering down of rocks and releasing sulfur that was stored. Once released the sulfur comes into contact with air and then is converted in sulfate, which is taken up by plants and microorganisms and moves through the food chain. When an organism dies and decomposes the sulfur is then again released as sulfate. In some cases, it is released into the Earth’s atmosphere, for examples volcanic eruptions or even the evaporation of water. Since the Industrial Revolution we as humans have greatly changed the amount of sulfur that is released into the Earth’s atmosphere such as the burning of fossil fuels. When the sulfur combines with the other
Acid is the chemical agent that reacts to dioxide. Paper will loses it durability and strength when it reaction to the oxidized. One of the chemical acids is sulphur dioxide that reacts in polluted air.
The primary source of sulfur dioxide in the atmosphere is from modern industrial action that processes substances containing sulfur. An example is the generation of power and electricity from coal, oil or gas that contains sulfur (burning fossil fuels). Sulfur dioxide is genuinely responsive and reactive in the air. At the point when sulfur dioxide does combine and respond with the water and air (hydrosphere and atmosphere) it forms sulfuric acid, which is the key component to acid rain. Acid downpour can result in deforestation, acidify soils (lithosphere), lakes and streams to the detriment of aquatic wildlife (biosphere), and can also affect human life. When combined with water, acids don't dissipate, and unless the particles bond with something
When leaves of a plant are exposed to acid rain, the outer waxy layer of tissue is disintegrated. The outer layer of tissue protects the plant from drying out, resulting in the disintegration of chloroplasts that drive photosynthesis. When humans burn fossil fuels, sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere. These chemical gases react with water, oxygen, and other substances to form mild solutions of sulfuric and nitric acid. This then creates acid
In addition to sulfur depletion, we are also consistently bombarded on the daily basis with chemical, food, and environmental toxicity coming from genetically-modified foods, processed foods, pasteurization processing, air-born pollutants, chemtrails that poison our air, water and soil with toxic metals, preservatives in the food, artificial food coloring, pharmaceutical
Sulfur aerosols are very dangerous natural gases formed when sulfur melts at around fifty degrees fahrenheit that are usually released into the atmosphere at great heights. They mix with ash and other debris, forming large plumes that can travel across the sky for miles. They also go very high into the sky, spreading out in every direction. These giant plumes of sulfur aerosols form deep in the earth inside volcanoes until enough pressure and gas build up and they are injected into the air. These plumes are still present after a year, and disappear after two years.
In contrast to this, sulphur dioxide, which also condenses to create acid rain, plays a more critical role in climate change. This is specifically seen in the fluctuation in global temperatures. Mills(2000) posits that sulphur dioxide is responsible for the major stratospheric perturbations. Harpp(2005), Grotzinger and Jordan(2014) and Self(2009) agree with this however Self(2009) argues that the impacts of other gases on climate change should also be studied in detail. It is reported by both Grotzinger and Jordan(2014) and Self(2009) that the presence of the sulphur dioxide gas in the stratosphere will result in the cooling down of the global temperatures. This is corroborated by both Harpp(2005) and Mills(2000), however they also argue that
The sulfur dioxide has great detriment for plants and human beings. Its toxicity is large and has corrosivity and decomposability. “Sulphur is a highly noxious venom for people's health, although we can be more resistant than other creatures that live with us. For example, the level of 0,3 µg per cubic metre of air implies a potential risk for human health, but for trees, 0,2 µg is extremely dangerous. In 1956, the London smog (caused by sulfuric acid mist) led to more than 4700 deaths. The pollution of sulfur dioxide has direct effect on human beings and animals’ life. When human body absorbs the sulfur trioxide or sulfuric acid mist formed by sulfur dioxide, its stimulation and detriment would be more significant, even though its density is only 1/10 of sulfur dioxide. Some experiments have proved that the physiological reaction caused by sulfuric acid mist is four times of sulfur dioxide. If he density of sulfur dioxide increases double each year, the death rate would increase by 11%.
Acid rain can cause reproductive defects on fish and other aquatic life. It can destroy aquatic ecosystems, leaving only a clear, but empty body of water. Acid rain was a problem in 1980, and steps were taken in order to fix it, and since then, air quality improved and will continue to improve as more and more steps are taken to control pollution. Modern technologies such as a cars, power plants, and factories consume fossil fuels in order to run. By consuming fossil fuels, cars, power plants, and factories release harmful gases into the air. These harmful gases then react with water droplets in the clouds to produce nitric and sulfuric acids, which turns normal precipitation into acid precipitation.
