Hygroscopic (absorbs moisture from the air). Corrosive to metal. The 98.3% grade is more stable in storage, and is the usual form of what is described as "concentrated sulfuric acid". Concentrated sulfuric(VI) acid . Alkenes react with concentrated sulfuric acid in the cold to produce alkyl hydrogensulphates. MDL number MFCD00064589. In one of its most familiar applications, sulfuric acid serves as the electrolyte in lead-acid storage batteries. It causes severe skin burns and eye damage. NACRES NA.22 Linear Formula H 2 SO 4. PubChem Substance ID 24860672. Concentrated Sulfuric Acid (H 2 SO 4) 93%-98% The use of concentrated sulfuric acid for pH control in water and wastewater treatment, agriculture, bio-energy and chemical processes is often the best choice due to the ready availability, low cost and effectiveness of this acid. Sulfuric acid can also be heated and used to dissolve other metals, including lead and copper.. Acid-proof synthetic gloves should be worn when working with sulfuric acid. Physical properties Grades of sulfuric acid. The electrophilic addition reaction between ethene and sulfuric acid. Concentrated sulfuric acid reacts violently with water and many other substances under certain conditions. 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. The concentrated sulphuric acid can act both as an acid and as an oxidising agent. The next thing to do is to take a good look at the sulfuric acid spill, making note of how big of an area it covers and the approximate volume present. The concentrated sulphuric acid gives a hydrogen ion to the halide ion to produce a hydrogen halide. Beilstein/REAXYS Number 2037554 . May cause irreversible eye injury. CORROSIVE: DANGER. 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. It is used to make fertilizer and a variety of other products. Target Organs: Lungs, teeth, eyes, skin. Because this is a gas, it immediately escapes from the system. It reacts violently, becoming very hot, when mixed with water. Assess the Situation. Potential Health Effects Eye: Causes severe eye burns. Sulfuric acid fumes can be dangerous to breathe and you don’t want to spread them any farther than you have to within an enclosed space. Molecular Weight 98.08 . May cause lung damage. Concentrated sulphuric acid acting as an acid. For a 15-minute exposure, the vapour concentration in the atmosphere should not exceed 0.15 mg m-3. Sulfuric acid 99.999% CAS Number 7664-93-9. EC Number 231-639-5. Concentrated sulfuric acid is a chemical used for multiple purposes by manufacturers and processors. For example, ethene reacts to give ethyl hydrogensulphate. \[ \ce{CH_2=CH_2 + H_2SO_4 \rightarrow CH_3CH_2OSO_2OH}\] It is also used as a drying agent by manufacturers.
