Sulfur dioxide (IUPAC-recommended spelling) or sulphur dioxide (traditional Commonwealth English) is the chemical compound with the formula S O 2. It is a colorless gas with a pungent smell that is responsible for the odor of burnt matches.

二氧化硫（英語： sulphur dioxide , sulfur dioxide ）是最常见的硫氧化物，化学式是SO 2 。无色气体，有强烈刺激性气味。大气主要污染物之一。火山爆发时会喷出该气体，在许多工业过程中也会产生二氧化硫。

二氧化硫 （英語： sulphur dioxide , sulfur dioxide）是最常見的 硫氧化物， 化學式 是SO 2。 無色氣體，有強烈刺激性氣味。 大氣 主要污染物之一。 火山爆發 時會噴出該氣體，在許多工業過程中也會產生二氧化硫。 由於 煤 和 石油 通常都含有硫化合物，因此 燃燒 時會生成二氧化硫。 當二氧化硫溶於水中，會形成 亞硫酸 （酸雨 的主要成分）。 若把SO 2 進一步氧化，通常在催化劑如 二氧化氮 的存在下，便會生成 硫酸。 [6] 這就是對使用這些燃料作為能源的環境效果的擔心的 …

二氧化硫（Sulfur Dioxide），化学式为SO2，是最简单和常见的硫氧化物，常温常压下为无色透明、有刺激性臭味的气体，易溶于水、乙醇、乙醚，溶于水形成具有漂白性的二元中强酸亚硫酸（H2SO3），与有机色素结合可形成无色化合物。

4 天之前 · Sulfur dioxide is an inorganic compound and is a heavy, colorless, poisonous gas. It is produced in huge quantities in intermediate steps of sulfuric acid manufacture. It is a serious air pollutant and contributes to the formation of acid rain.

Sulfur dioxide (SO2) was previously regarded as a toxic gas in atmospheric pollutants. But it has been found to be endogenously generated from metabolism of sulfur-containing amino acids in mammals through transamination by aspartate aminotransferase (AAT). SO2 could be produced in cardiovascular tissues catalyzed by its synthase AAT.

Sulfur dioxide, SO2, is a colourless gas or liquid that has a strong, odorous smell. It is derived from the burning of fossil fuels (coal and oil) and the smelting of sulphur-containing mineral ores (aluminium, copper, zinc, lead and iron). The sulfur dioxide quickly dissolves to form sulfuric acid in …

2025年1月10日 · EPA’s national and regional rules to reduce emissions of SO 2 and pollutants that form sulfur oxides (SO x) will help state and local governments meet the Agency’s national air quality standards. Learn about how air quality standards help reduce SO 2

2012年12月27日 · Both sulfur and oxygen have 6 electrons in their outermost shell. Since both only need two electrons to stabilize, why doesn't just one atom of oxygen react with one sulfur atom, forming sulfur monoxide SO instead of sulfur dioxide $\ce{SO2}$?

2017年5月9日 · To form the Lewis structure of Sulfur Dioxide, we need first to determine the number of valence electrons available. These valence electrons act as the building blocks of the structure. They are found in the atom’s outermost shell, where the force of attraction from the nucleus is the weakest.
