When you were still in your chemistry class, you often heard the term Sulfuric Acid. You knew that it is a very corrosive liquid that is also odorless, colorless and very dangerous. You were surprised as to why such a seemingly hazardous and useless substance has come into creation. Well, this is because you do not have any idea about its uses in our society.
Sulfuric acid is usually produced in mining. It is formed when metallic ores are. Most ores are sulfides and the melting operation, sulfur dioxide gas is produced. Thanks to technological advances, this can now be contained gas. Together with the containment of the gas can be processed to create sulfuric acid. Water is sprayed on the gas and then it is cleaned, chilled, dried, and then to walk in a catalytic converter. After he received will be used in the catalyst, the product is then mixed with water. The mixture would then sulfuric acid, so you get to H2SO4. The Belgian Johann Van Helmont is preparing the first person to the chemical.
The acid is known that a very strong pollutant. But even with the dangers associated, the acid is also very useful in some industries. Needless to say, has become a very important industrial chemical. In fact, because of its importance, it is estimated that in the United States alone, sometime in 1990, where around forty million tons of this chemical were produced. What do calls for this amount of the chemical? Here are some of the industries, the benefits to come with the acid.
Agricultural industry will be used in the manufacture of manure. In fact, it is 60-5% of acid production was only found to be in this industry.
The chemical industry, perfume, paper, medicines, adhesives, cellophane, pigments, film, plastic, etc., are used to generate a common byproduct of several industries, phosphoric acid, substances such as nitric acid, the hydrochloric acid. Acid and explosives TNT (trinitrotoluene) is used to create certain types of explosives.
The petroleum industry also needs to use the acid in removing tarry compounds and sulphur in the petroleum.
Using the acid for purification of gold metallurgy, metal, metal, coated, prior to the extraction of copper pickling.
Battery uses a sulfuric acid electrolyte to function as a medium of the battery. This acid batteries can be found in general to lead. Acid is particularly useful like a car.
In laboratories, the acid is used as dehydrating agent, reagent and drying agent.
But there are many uses for sulfuric acid. However, we must bear in mind that the dangers that come with the handling of these chemicals. Therefore, caution is the risk measures are to be observed in the use of acid.
In the laboratory, we must pay attention to the former water contact with the acid, the strong exothermic reaction, with the latter. In acid and water mixture may cause burns, far more than other acids cause severe burns. The mixture, not only from the acid and water led to a mixture of burning calories, but can also cause dehydration and lead to tissue damage. In dealing with this situation, you need to remove any contact with the acid and water, clothing. Then, you need to keep water for 10-15 minutes, wash the affected areas. This will help to slow down surrounding areas, to prevent other damage.
