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".

Persons who have drawn concentrated sulfuric acid into a pipet with oral suction, and obtained the acid on the tongue through poor technique, report that it tastes sweet before the onset of corrosive action.

Sulfuric acid is a strong mineral acid, that is commonly used in organic synthesis as a reagent, catalyst, and solvent. It is also useful to perform several functions, including dehydration, sulfonation, and nitration.

2021年1月12日 · ACGIH: Documentation of the Threshold Limit Values (TLVs) and Biological Exposure Indices (BEIs) - Sulfuric acid. See annual publication for most recent information. IARC Monographs Strong Acid Mists Containing Sulfuric Acid, 100-F, 2011.

2025年1月15日 · Sulfuric acid, dense, colorless, oily, corrosive liquid; one of the most important of all chemicals, prepared industrially by the reaction of water with sulfur trioxide. In one of its most familiar applications, sulfuric acid serves as the electrolyte in lead-acid storage batteries.

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].

2025年1月27日 · Concentrated sulfuric acid is a highly corrosive liquid that can cause severe, deep burns upon skin contact. The concentrated acid destroys tissue because of its dehydrating action, while dilute H 2SO4 acts as a skin irritant because of its acid character.

• 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

2024年10月2日 · When it comes to handling chemicals safely, having a comprehensive Concentrated Sulfuric Acid SDS (Safety Data Sheet) is essential. This document provides vital information regarding the hazards, safe handling practices, and emergency measures for concentrated sulfuric acid.

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.
