Sulfuric acid (H2S04) is a corrosive substance, destructive to the skin, eyes, teeth, and lungs. Severe exposure can result in death. Workers may be harmed from exposure to sulfuric acid. The NIOSH Manual of Analytical Methods (NMAM) is a collection of methods for sampling and analysis of contaminants in workplace air, and in the blood and Handbook of Sulphuric Acid Manufacturing Douglas K. Louie DKL Engineering, Inc., 2005 - Sulfuric acid - 1450 pages 4 Reviews What people are saying - Write a review User Review - Flag as Acid sulfate soils is the common name given to naturally occurring soil and sediment containing iron sulfides. When these natural occurring sulfides are disturbed and exposed to air, oxidation occurs and sulfuric acid is ultimately produced. For every tonne of sulfidic material that completely oxidises, 1.6 tonnes of pure sulfuric acid is produced. The formula for sulfuric acid is #H_2SO_4#. One magnesium atom, two hydrogen atomic spheres, and one sulfate ion are present on each side. As written, the charges are balanced and therefore the reaction is balanced. Magne sulfate and hydrogen gas are the product of the reaction. The process uses concentrated sulphuric acid as part of the catalysis system and as a carrier in the reactor train. The MMA product is boiled of leaving an aqueous solution (spent acid) of ammonium sulphate, sulphuric acid and various organic compounds. Approximately 3 tonnes of spent acid is produced for every tonne of MMA produced. Pure sulfuric acid has a specific gravity of 1.830 at 25 °C (77 °F); it freezes at 10.37 °C (50.7 °F). When heated, the pure acid partially decomposes into water and sulfur trioxide; the latter escapes as a vapour until the concentration of the acid falls to 98.3 percent. This mixture of sulfuric acid and water boils at a constant Concentrated sulfuric acid is a strong oxidant and reacts violently with combustible and reducing materials. The substance is a strong acid: it reacts violently with bases and is corrosive to most common metals, forming a flammable/explosive hydrogen gas. Sulfuric acid reacts violently with water and organic materials with evolution of heat. A feature of all metallurgical sulphuric acid plants is the gas cleaning system which cleans and conditions the gas prior entering the contact section of the acid plant. The first step is to quench and cool the gas in a quench/humidifying tower. This process reduces the temperature, partially cleans and humidifies the gas. Sulfuric acid can cause irritation of the eyes, nose, and throat. Breathing in the mist or vapor can cause difficulty in breathing, teeth erosion or the mouth to become sore.
