Sulphuric acid 98%
Sulfuric acid (HSO) at a concentration of 98% is one of the most widely used industrial chemicals due to its strong acidic properties and versatility.
Properties of 98% Sulfuric Acid
Chemical Formula: HSO

Concentration: 98% (remaining 2% is water)

Appearance: Colorless, oily liquid

Density: ~1.84 g/cm³ (highly dense)

Boiling Point: ~337°C (639°F)

Melting Point: ~10°C (50°F)

Corrosivity: Highly corrosive to metals, organic materials, and human tissue.

Hygroscopicity: Absorbs moisture from the air, making it a strong dehydrating agent.
Applications of 98% Sulfuric Acid
98% sulfuric acid is a key raw material in numerous industries due to its strong acidic and dehydrating properties. Major applications include:

1. Fertilizer Production
Used in the manufacture of phosphate fertilizers (e.g., superphosphate and ammonium sulfate).

Reacts with phosphate rock to produce phosphoric acid, a key fertilizer ingredient.

2. Chemical Manufacturing
Production of chemicals such as hydrochloric acid, nitric acid, and sulfate salts.

Used as a catalyst or reagent in organic synthesis (e.g., sulfonation, alkylation).

3. Petroleum Refining
Used in alkylation processes to produce high-octane gasoline.

Purification of petroleum products by removing impurities.

4. Metal Processing
Pickling and Cleaning: Removes rust and scale from steel and iron surfaces.

Used in the production of copper, zinc, and other metals.

5. Water Treatment
pH adjustment and neutralization in wastewater treatment plants.

6. Textile Industry
Used in dyeing processes and the production of synthetic fibers.

7. Battery Manufacturing
Key component in lead-acid batteries (though typically at lower concentrations, around 30-50%).

8. Dehydrating Agent
Used in laboratories and industries to remove water from gases and organic compounds.
