Sulfuric acid - Wikipedia
Although nearly 100% sulfuric acid solutions can be made, the subsequent loss of SO 3 at the boiling point brings the concentration to 98.3% acid. The 98.3% grade, which is more stable in storage, is the usual form of what is described as "concentrated sulfuric acid".

Sulfuric acid (concentrated) is extremely hazardous in contact with carbides, bromates, chlorates, fulminates, picrates, and powdered metals [Haz. Chem. Data 1966]. Allyl chloride may polymerize violently under conditions involving an acid catalyst, such as sulfuric acid [Ventrone 1971].
Comprehensive Guide to Sulfuric Acid: Uses, Handling, Safety, …
2024年1月29日 · Each grade of sulfuric acid, defined by its concentration and purity, finds its niche in specific applications. This versatility not only highlights the importance of sulfuric acid in various sectors but also underscores the necessity of understanding its different forms to utilize it effectively and safely.
Sulfuric Acid - an overview | ScienceDirect Topics
Concentrated sulfuric acid contains about 98% of the acid, which is equivalent to an 18 M solution. There is extensive hydrogen bonding as indicated by the high viscosity and boiling point of the liquid.
• Sulfuric acid is noncombustible, but can cause finely divided combustible substances to ignite. • Sulfuric acid (especially dilute) reacts with most metals to produce hydrogen gas which is flammable and potentially explosive. • Concentrated sulfuric acid is highly corrosive and can cause severe burns upon skin
Sulphuric Acid: Preparations, Properties, Uses, Health Risks
2023年9月23日 · The most stable form is concentrated sulfuric acid, which is 98% water. Many more concentrations with different names are available for diverse purposes, such as battery acid (29-32%), chamber acid (62-70%), and tower acid (78-80%).
Strong inorganic acid mists containing sulfuric acid may cause cancer. Concentrated sulfuric acid reacts violently with water and many other substances under certain conditions.
concentrated acid has a freezing point of 10.4oC and boiling point of 338 o C, whereby it begins to decompose into sulphur trioxide (highly corrosive and toxic) and steam.
