Coal burning power plants Almost all the sulphur dioxide in the air comes from industrial sources. Industrial smelters, which obtain metals from sulphide ores, produce tones of sulphur dioxide daily.
Sulfur dioxide (also sulphur dioxide) is the chemical compound with the formula SO 2. At standard atmosphere, it is a toxic gas with a pungent, irritating, and rotten smell. The triple point is 197.69 K and 1.67 kPa. It is released naturally by volcanic activity. Sulfur dioxide is primarily produced for sulfuric acid manufacture (see contact process). In the United States in 1979, 23.6 million tonnes of sulfur dioxide were used in this way, compared with 150 thousand tonnes used for other purposes. Chemical reference number (CAS). Sulfur dioxide, SO 2, is a colorless gas or liquid with a strong, choking odor. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores (aluminum, copper, zinc, lead and iron) that contain sulfur. Sulfur dioxide dissolves easily in water to form sulfuric acid. Sulfur dioxide is a colorless gas with a pungent and suffocating odor, similar to a just-struck match. It has an acidic taste and is a liquid when under pressure. Sulfur dioxide is formed when fuel containing sulfur, such as coal and oil, is burned. The chemical symbol for sulfur dioxide is SO2. Most sulfur dioxide in the air comes from the burning of coal and oil at electric power plants. Other sources of sulfur dioxide in the air are industrial facilities that use coal or oil, petroleum refineries, cement manufacturing, metal processing, paper pulp manufacturing, and copper smelting.  Answers. Best Answer: Almost all the sulphur dioxide in the air comes from industrial sources. Industrial smelters, which obtain metals from sulphide ores, produce tones of sulphur dioxide daily. Half of the output of sulphur dioxide comes from the burning of coal. All coal contains between 0.5 and 5 percent sulphur. The sulphur dioxide escapes up chimneys into the atmosphere. Worldwide, 150 million tones a year are emitted Sulfur dioxide (SO2) is a gas that is prevalent in crude oil, coal, and ore that contains common metals like aluminum, copper, zinc, lead and iron. Where does it come from? SO2 is formed when fuel-containing sulfur is burned and when gasoline is extracted from oil, or when metals are extracted from ore. Once it is released into the atmosphere, SO2 dissolves in water vapor to form acid (acid rain). The majority of SO2 released into the atmosphere comes from coal burning power plants. Other sources of this pollutant are petroleum refineries, cement manufacturing, and metal processing facilities. Most of the sulfur dioxide released into the environment comes from electric utilities, especially those that burn coal. Some other sources of sulfur dioxide include petroleum refineries, cement manufacturing, paper pulp manufacturing and metal smelting and processing facilities. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores (aluminum, copper, zinc, lead and iron) that contain sulfur. Sulfur dioxide dissolves easily in water to form sulfuric acid. Comes from industrial process. Sulfur dioxide has the formula SO2. It is formed by burning sulfur, which is an impurity in coal and crude oil, with oxygen in the air. No, sulfur dioxide is a gas with the formula SO2 Sulfite is an ion with the formula (SO32-). It occurs along side some sort of positive ion to balance its negative charge. Th … ese compounds, called sulfites, can form when sulfur dioxide, an acidic oxide, reacts with basic oxides. Most metal oxides are basic
