Additionally, sulfuric acid is essential for the manufacture of ammonium sulfate fertilizer, which is essential for replenishing sulfur levels in the soil. Due to its high exothermic properties and easy water dissolution, this acid generates substantial heat during the reaction. Sulfuric acid reacts with metals, with the rate of response intensifying at elevated temperatures. As a hazardous substance, sulfuric acid is subject to rigorous regulation. This product is manufactured by Kimia Daran Kavir Company, which is among its largest producers throughout the country.
