Natural activities that increase sulfur dioxide (SO2) levels include volcanic eruptions, where magma releases gases containing sulfur, and wildfires, which can produce SO2 from burning organic material. Additionally, the decomposition of organic matter and certain biological processes in wetlands can contribute to sulfur emissions. These natural sources can significantly impact air quality and contribute to atmospheric sulfur levels.
Sulfur dioxide is released into the atmosphere primarily through human activities such as burning of fossil fuels like coal and oil, and industrial processes like metal smelting. It can also be released by natural sources like volcanic eruptions.
Burning of fossil
Burning of fossil fuels
It is a mineral. Sulphur dioxide certainly is not a lipid.
Burning coal (a fossil fuel) releases carbon dioxide and sulphur dioxide.
Sulphur dioxide is an ACIDIC gas. When it is dissolved in water it form the acid ; SULPHUROUS ACID ( H2SO3). Note the spelling and the number of oxygen atoms in combination. NB The oxides of non-metallic elements on the right hand side of the Periodic Table all produce acids. e.g. Carbon Dioxide/Carbonic Acid . Nitrogen dioxide/Nitric Acid, Phosphorus oxides/phossphoric acid. etc., NNNB The metal oxides on the left hand side of the Periodic Table produce bases/alkalis.
Sulphur dioxide is produced in petrol engines due to the combustion of sulphur-containing compounds present in the fuel. When these compounds are burned, they react with oxygen to form sulphur dioxide as a byproduct, which is then emitted through the exhaust. Reducing the sulphur content in petrol can help minimize the production of sulphur dioxide emissions.
Oxygen!!! However, you do NOT add oxygen, it is combined. Yellow elemental sulphur is heated in a flow of oxygen gas. The product is sulphur dioxide. It has a very acrid/acidic smell, so do NOT breath it in. Sulphur dioxide can be dissolved in water to form Sulphurous Acid. The reaction equation for the combination of sulphur and oxygen is ; - S(s) + O2(g) == heat==> SO2(g) The reaction equation for the combination of sulphur dioxide and water is:- SO2(g) + H2O(l) == H2SO3(aq) NOTE this is sulphurOUS Acid. SulphurIC Acid has the formula ' H2SO4 '. one extra oxygen in combination.
The atmosphere doesn't produce any sulphur dioxide. It receives a fair bit from various human activities though.
Some petroleum fuels such as Bunker C or heavy diesel contain significant amounts of sulphidic compounds and some natural fuel gases are known as sour when they contain hydrogen sulfide. In both of these cases when the fuels are burned they will produce sulphur dioxide. In automotive diesel there is a small amount of sulphur. This, because of the combustion conditions, is not released as sulpur dioxide, but as solid sulfate particulate. Fuels which contain no sulphur (refined and treaterd by sulphur removal) do not give off sulphur dioxide.
sulphur dioxide
Sulphur dioxide (SO2) is the compound formed when sulphur reacts with oxygen.
