Sulfuric acid is a key ingredient in the manufacture of phosphate fertilizers, such as superphosphate and ammonium phosphate. It is used to convert phosphate Rock into water-soluble forms that plants can readily absorb, promoting crop growth and increasing agricultural productivity. Sulfuric acid is widely employed in the production of various chemicals. It serves as a catalyst or reactant in the synthesis of substances like dyes, pigments, detergents, synthetic fibers, plastics, pharmaceuticals, and explosives. It is an essential component in the manufacturing processes of materials like nylon, rayon, and detergents.

Sulfuric acid is utilized in water treatment processes to adjust the pH levels, neutralize alkaline water, and control the growth of bacteria and algae. It helps in maintaining the desired Chemical balance and disinfecting water supplies. Sulfuric acid finds applications in the Petrochemical sector. It is used as a catalyst in various chemical reactions, such as the alkylation process for the production of alkylates, which are valuable components in gasoline. Sulfuric acid is also employed in the purification and treatment of Petroleum products.

Sulfuric acid is used in the dyeing process of textiles, particularly for cotton and other natural fibers. It helps to improve the absorption and fixation of dyes, enhancing color fastness and overall dyeing efficiency. Sulfuric acid is commonly used in laboratories for pH adjustment, particularly in analytical and research applications. It is utilized in experiments and chemical analysis procedures to create acidic conditions or neutralize alkaline solutions. Sulfuric acid is a powerful dehydrating agent due to its ability to remove water molecules from substances. It is used in various dehydration processes, such as the removal of water from organic compounds, sugars, and gases.

The main application of sulfuric acid is in the production of phosphate fertilizers. The strategic importance of sulfuric acid is in line with this. With the increasing population of the world and the limitation of agricultural lands, the productivity and efficiency of production of Crops from soil per unit, must necessarily be increased to be able to meet the growing population needs. Today, this is no longer done with animal manures. Because animal manures only change the physics of the soil and prepare the soil for growth, they are very poor in nutrients for the plant.

The use of chemical fertilizers is a well-known necessity to increase soil productivity. As mentioned in the applications section, sulfuric acid is used in the production of high-consumption fertilizers such as phosphate fertilizers and ammonium sulfate fertilizers, and in such applications cannot be replaced with any other substance, it is very important in that regard. In the oil refining industry, an acid is commonly used as a catalyst. Sulfuric acid is one of these important catalysts. This substance is used in SAAU unit or sulfuric acid Alkylation unit.

Sulfuric acid is employed in the cleaning and descaling of industrial equipment, pipes, and tanks. It helps to dissolve and remove mineral deposits, rust, and scales that accumulate over time. Sulfuric acid is a major component in various types of batteries. The acid of battery contains 35% H2SO4. These types of batteries include high-power batteries such as batteries in hospital imaging equipment, car batteries, agricultural equipment batteries, and so on.

Sulfuric acid is used in Metal processing operations, including pickling and cleaning metal surfaces to remove rust, scale, or oxidation. It prepares metal surfaces for further treatment, such as plating, painting, or soldering. Sulfuric acid is also involved in the extraction of Metals from ores and the refining of metals like copper, zinc, and nickel. Sulfuric acid plays a crucial role in the production of lead-acid batteries, commonly used in automotive, industrial, and backup power applications. It acts as an electrolyte that facilitates the flow of ions between the battery's positive and negative electrodes, generating electricity.
