Sulfuric Acid

Appearance: Colorless, highly concentrated liquid

Chemical Name: Sulphuric Acid

Chemical Formula: H2SO4

Properties: It can be dissolved in water at any concentration.

Packaging Type: Drum, IBC, Tanker

Definition and Areas of Use:

Sulfuric acid is a colorless and oily liquid with the chemical formula H2SO4. It is a very important strong acid in industry. It is the most widely used product in the chemical industry that dissolves in water. It is also known as battery acid, zac oil or zac acid. Its density is 1.834 at 25 degrees when pure. It freezes at 10.5 degrees and boils at 315-318 degrees. When mixed with water, a high temperature is released. Since it can cause dangerous splashes, instead of adding water to acid when mixing with water, acid should be added to water. Since it is dangerous to human health, all necessary precautions should be taken and intervention should be made in case of contact with the skin. Since the interventions to be made for acids are different, the skin to be applied for sulfuric acid should be dried immediately and washed with water. Initially, washing with water should not be attempted.

Sulfuric acid, which is not found pure in nature, is produced in the industrial field by the contact method or by lead chambers. Here, sulfur dioxide is converted to sulfur trioxide by oxidation with oxygen using different catalysts, and sulfur dioxide is reacted with water to obtain sulfuric acid. This acid is used in various concentrations in dyes, fertilizers, explosives, pigments, pesticides, petroleum refining, inorganic salts and metallurgy. It is also used in the production of some batteries. It has the ability to conduct electricity. Sulfuric acids on the market are usually 78.93 - 98% concentrated.

Concentrated sulfuric acid contains 96-98% H2SO4 and its properties are close to water. In contact, it draws water from many organic substances and creates a heat-producing reaction. Therefore, it damages the skin. Care should be taken when diluting sulfuric acid. Water causes an exothermic reaction, forming bubbles on the surface of the acid and boiling suddenly. It reacts with oxygen and forms sulfur trioxide, but this occurs slowly. Any concentration of sulfuric acid is harmful to the eyes. It causes an itching effect on the skin and causes serious burns.

Areas of Use

  • It is possible to see that this acid, which is used in many areas in the industry, is used especially in fertilizer production, ammonium sulphate production, paint industry, explosive production and petrochemical industry.
  • Sulfuric acid, formula H2SO4, is a very strong mineral acid. It can be dissolved in water at any concentration. It is possible to see that it is produced in industry using the contact method or the lead chamber method. Sulfuric acid is used in various concentrations in fertilizer, pigment, dye, explosive, 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 known as battery acid among the public. It is a substance that conducts electricity and produces very high heat when dissolved in water.
