It is prepared on an industrial scale as a precursor to sulfuric acid. Sulfur trioxide exists in several forms: gaseous monomer, crystalline trimer, and solid polymer. Sulfur trioxide is a solid at just below room temperature with a relatively narrow liquid range. Gaseous SO 3 is the primary precursor to acid rain. [6]
Sulfur trioxide, SO 3, a chemical compound of sulfur and the anhydride of sulfuric acid; Sulfite, SO 2− 3, a chemical ion composed of sulfur and oxygen with a 2− charge; SO(3), the special orthogonal group in 3 dimensions; the rotations that can be given an object in 3-space; Star Ocean: Till the End of Time, the third main game in the Star ...
Sulfuric acid itself is regenerated by dilution of part of the oleum. The lead chamber process for sulfuric acid production was abandoned, partly because it could not produce sulfur trioxide or concentrated sulfuric acid directly due to corrosion of the lead, and absorption of NO 2 gas. Until this process was made obsolete by the contact ...
This combustion process produces gaseous sulfur dioxide (SO 2) and sulfur trioxide (SO 3) which are then used to manufacture "new" sulfuric acid. Hydrogen peroxide ( H 2 O 2 ) can be added to sulfuric acid to produce piranha solution , a powerful but very toxic cleaning solution with which substrate surfaces can be cleaned.
Sulfur dioxide is an intermediate in the production of sulfuric acid, being converted to sulfur trioxide, and then to oleum, which is made into sulfuric acid. Sulfur dioxide for this purpose is made when sulfur combines with oxygen. The method of converting sulfur dioxide to sulfuric acid is called the contact process. Several million tons are ...
Scientists warn that if carbon dioxide and other greenhouse gas emissions continue to rise at their current rates, Earth’s temperatures could increase dramatically in future decades, leading to catastrophic and irreversible climate change. The 10 largest emitters produced about 26.4 gigatons of carbon dioxide in 2013.
A video captured a tornado ripping through a shopping center parking lot in California over the weekend. The Santa Cruz Sentinel reported that the tornado in Scotts Valley on Saturday caused ...
Treatment of sulfur with hydrogen gives hydrogen sulfide.When dissolved in water, hydrogen sulfide is mildly acidic: [5] H 2 S ⇌ HS − + H +. Hydrogen sulfide gas and the hydrosulfide anion are extremely toxic to mammals, due to their inhibition of the oxygen-carrying capacity of hemoglobin and certain cytochromes in a manner analogous to cyanide and azide.
