Definition and Usage Areas of Sulfuric acid
Sulfuric acid is a colorless and oily liquid with the chemical formula H2SO4. It is a strong acid, which is very important in the industry. It is water-soluble and the most used product in the chemical industry. Battery acid is also known as zac oil or zac acid. In its pure state, its density at 25 degrees is 1.834. It freezes at 10.5 degrees and boils at 315-318 degrees. When mixed with water, a high temperature is released. Acid should be added to the water instead of adding the water to the acid when mixing with water, as it can cause dangerous splashes. Since it is dangerous to human health, all necessary precautions should be taken and intervened in case of skin contact. Since the interventions for acids are different, the skin to be applied for sulfuric acid should be immediately dried and washed with water. Initially, it should not be attempted to wash with water.
Sulfuric acid, which is not found pure in nature, is produced in the industrial field by contact method or through lead chambers. Here, sulfur dioxide is oxidized with oxygen by different catalysts and converted to sulfur trioxide, and sulfur dioxide is reacted with water and sulfuric acid is obtained. This acid is used in various concentrations in the fields of dyestuff, fertilizer, explosive material, pigment, pesticide, petroleum refining, inorganic salt, and metallurgy. It is also used in the making of some batteries. It has the ability to conduct electricity. Sulfuric acids in the market are generally 78.93 – 98% concentrated.
It contains 96-98% H2SO4 in concentrated sulfuric acid content and its properties are close to water. On contact, it draws water from a large number of organic materials and creates an exothermic reaction. Therefore, it harms the skin. Care should be taken when diluting sulfuric acid. Water causes an exothermic reaction, creating bubbles on the surface of the acid and boiling suddenly. It reacts with oxygen to form sulfur trioxide, but this happens slowly. Any concentration of sulfuric acid is harmful to the eyes. It causes itching on the skin and causes severe burns.
- It is possible to see that this acid, which is used in many areas of the industry, is used especially in fertilizer production, ammonium sulfate production, paint industry, explosive production, and petrochemical industry.
- Sulfuric acid, with the formula H2SO4, is a very strong mineral acid. It is possible to dissolve in water at any concentration. It is possible to see that it is produced using the contact method in the industry or by using the lead chamber method. Sulfuric acid in various concentrations is used in fertilizer, pigment, dyestuff, explosive material, pesticide, inorganic salt and petroleum refining, and metallurgy processes. In addition to these, it is possible to see that sulfuric acid is used in the production of various batteries. We can say that this acid is popularly known as battery acid. It is a substance that conducts electricity and produces very high heat when dissolved in water.
