Sulfuric acid | Wikipedia Encyclopaedia Wiki | Fandom
Sulfuric acid (alternative spelling sulphuric acid) is a mineral acid with molecular formula H2SO4. It is a colorless odorless syrupy liquid that is soluble in water, in a reaction that is highly exothermic. Its corrosiveness can be mainly ascribed to its strong acidic nature. It is also hygroscopic, readily absorbing water vapour from the air. Sulfuric acid at even moderate concentrations is

2020/8/16· Sulfuric acid, sulfuric also spelled sulphuric (H 2 SO 4), also called oil of vitriol, or hydrogen sulfate, dense, colourless, oily, corrosive liquid; one of the most commercially important of all chemicals.Sulfuric acid is prepared industrially by the reaction of water with sulfur trioxide (see sulfur oxide), which in turn is made by chemical coination of sulfur dioxide and oxygen either by
Why Car Batteries Are Dangerous
2008/8/28· That is what releases the calcium metal and antimony IN A REACTIVE STATE into contact with sulfuric acid residues entrained in the lead dioxide/lead sulfate matrix of the battery plates. This small amount of entrained sulfuric acid cannot be washed out since it is both chemically and mechanically trapped in place until the lead backing plates are melted.
