Product Description

General description:

Chemical Formula: H2SO4

Sulfuric acid (H2SO4) is a mineral acid made of oxygen, hydrogen, and sulfur. It is also called oil of vitriol, battery acid, acido sulfur, and hydrogen sulfate. It is the third most largely manufactured industrial chemical. It is an odorless, viscous and colorless liquid that is soluble in water.
Sulfuric acid is a salient commodity chemical, and for any nation, the productions of Sulfuric acid are a good sign of its industrial influence. It is a corrosive chemical for metals and tissue and it has an oily, glassy appearance.
Sulfuric acid can cause harm to the body if short-term exposure to high concentrations or Long term exposure to low concentrations from inhalation.
Uses of sulphuric acid are to produce fertilizers and other chemicals, in steel and iron production, and in petroleum refining.

Application & Usage:

Sulfuric acid(h2so4) has many uses in different industries, such as mineral processing, petroleum refining, fertilizer production, and wastewater processing.
Uses of sulphuric acid is to produced fertilizers, mainly ammonium phosphate, superphosphates, and ammonium sulfates.
Sulfuric acid is the iron manufacturing industry, it is used to remove oxidation.
Sulfuric acid has many applications like producing pigments, dyes, cleaning agents, detergents, explos ives, and drugs.
In lead-acid batteries sulfuric acid is used as the electrolyte.
Major amount of sulfuric acid is used to produce phosphoric acid, calcium dihydrogen phosphate, phosphate fertilizers, and ammonium phosphates. It is also used to make ammonium sulfate, which is a particularly important fertilizer in sulfur-deficient.
Sulfuric acid is mostly used in metal processing in the production of copper and zinc. It also cleans the surface of the steel sheet, which is called pickling.
It is utilized to produce caprolactam, which is transformed into polyamide 6 and in the manufacture of titanium dioxide.
In many industries, Sulfuric acid is widely used to produce phenol and hydrofluoric acid with propanone.
In the household, it is used as a drain cleaner with other reactive property.
Many other industries use this chemical for, production of cleaning agents, wastewater processing, producing explo sives, processing of minerals, paper industry, and detergents manufacturing.
In the skincare industry uses of sulphuric acid is to make skin ointments to heal skin infections like canker sores.
Other uses are batteries manufacturing, potato farming, detergents making like trisodium phosphate, perfume manufacturing, printing ink manufacturing.

Widely Used in Diverse Industries

Sulphuric acid is an essential chemical across multiple industries, including fertilizers, chemical synthesis, petroleum refining, and metal processing. It serves as a key ingredient in manufacturing phosphate fertilizers, cleaning metals, generating batteries, and textile treatments. Its strong oxidizing properties and capacity to function as a dehydrating agent make it invaluable for various large-scale processes.

Safe Handling and Storage Recommendations

Given its high corrosivity and reactive nature, sulphuric acid must be stored in corrosion-resistant, tightly sealed containers in a cool and well-ventilated area. Direct contact with water, organic materials, and bases must be avoided to minimize the risk of violent reactions and contamination. Proper safety equipment such as acid-resistant gloves and face protection is mandatory during handling.

Physical and Chemical Characteristics

Sulphuric acid appears as a colorless to slightly yellow liquid, is odorless or carries a faint pungent smell, and possesses a high viscosity (22 mPas at 25C). It boasts a high boiling point (337C), density of 1.84 g/cm, and is miscible with water, releasing significant heat upon mixing. Its structural formula is O=S(=O)(O)O, and it is highly stable when handled according to guidelines.

FAQs of Sulphuric Acid:

Q: How should sulphuric acid be safely stored and transported?

A: Sulphuric acid must be stored in tightly sealed, corrosion-resistant containers, kept in cool, well-ventilated areas away from bases, organic materials, and moisture. Transportation should comply with Hazard Class 8 (Corrosive) regulations, and be identified with UN Number 1830 to ensure safe and legal handling.

Q: What are the primary applications and benefits of using sulphuric acid?

A: Sulphuric acids main uses include manufacturing phosphate fertilizers, refining petroleum, cleaning and processing metals, producing chemicals, and serving as battery acid in lead-acid batteries. Its benefits lie in its strong oxidizing and dehydrating properties that make many industrial and laboratory chemical processes more efficient.

Q: When should special precautions be taken during the handling of sulphuric acid?

A: Special precautions are essential at all times; however, particular care is needed when diluting or mixing sulphuric acid with water, as the reaction is intensely exothermic and can cause splattering. Always add acid carefully to water (never the reverse) and use proper personal protective equipment to prevent severe burns or injuries.

Q: Where is sulphuric acid most commonly utilized in industrial processes?

A: Sulphuric acid finds its most widespread industrial usage in the production of fertilizers (especially phosphates), wastewater treatment, petroleum refining, and the cleaning/pickling of metals. It is also used in battery manufacturing and various chemical syntheses.

Q: What makes sulphuric acid highly corrosive and hazardous?

A: Its extremely low pH (<1), strong dehydrating and oxidizing abilities, and reactivity with water and organic materials render sulphuric acid highly corrosive to metals and living tissue. This underlies its classification as a hazardous substance and necessitates strict handling protocols.

Q: How does the absence of volatile organic compounds (VOC) in sulphuric acid impact its usage?

A: The lack of VOCs in sulphuric acid means it does not contribute to air pollution via volatile emissions, making it preferable in regulated industrial environments where VOC emissions are restricted. However, this does not reduce its corrosive or toxic risks.
