sulfuric acid
Sulfuric acid (chemical formula H2SO4) is a highly corrosive strong mineral acid, usually transparent to yellowish, at any concentration can be miscible with water and exothermic. Sometimes, in the industrial manufacturing process, sulfuric acid may also be dyed dark brown to improve people's vigilance. Sulfuric acid as a dibasic acid has different properties at different concentrations, and its corrosiveness to different substances, such as metals, biological tissues, and even rocks, is rooted in its strong acidity and its strong concentration at high concentrations Dehydration and oxidation. Sulfuric acid can cause great damage to the flesh, because it will be through the acidic hydrolysis of decomposition of protein and fat caused by chemical burns, but also with the carbohydrate dehydration reaction and cause secondary flame burns; if accidentally, Will destroy the retina caused permanent blindness. Therefore, when used, should be done safety measures. In addition, sulfuric acid is also deliquescence, will absorb the water vapor in the air. Because sulfuric acid has different characteristics, it also has different applications, such as home strong acid channel agent, lead acid battery electrolyte, fertilizer, refinery materials and chemical synthesis agent. Sulfuric acid is widely produced, the most commonly used industrial method for contact method. ...
