Concentrated Sulfuric Acid 98% (Industrial Sulphuric Acid, Oil of Vitriol) (CAS 7664-93-9, MW 98.08 g/mol) is a heavy-duty industrial mineral acid supplied by Loc Thien Chemical as a Industrial Chemical Bulk Supplier to chemical complexes, pulp mills, and water treatment operations across Vietnam. Exhibiting a dense specific gravity of 1.840 g/cm³ at 20°C, this colorless to amber viscous liquid is a foundational chemical reagent utilized for synthesizing aluminum sulfate, ferrous sulfate, titanium dioxide, and neutralizing alkaline effluents. Loc Thien operates specialized 5–30-ton heavy-duty chemical road tankers, guaranteeing continuous deliveries with an immediate 15-minute quotation turnaround.
🛑 Mandatory EHS Operational Rule: Exothermic Hydration Safety
Concentrated sulfuric acid possesses an extreme chemical affinity for water, releasing immense hydration energy upon contact:
[Life Safety Golden Rule] ALWAYS add concentrated sulfuric acid slowly to cold water while vigorously agitating! NEVER add water to concentrated acid. Lighter water floats on dense acid (1.0 vs 1.84 g/cm³), flashing instantaneously to steam and violently erupting boiling 100°C concentrated acid into the operator's workspace, inflicting catastrophic third-degree burns.

Core Industrial Applications
1. Raw Material for Water Treatment Coagulants
Reacted with bauxite or aluminum hydroxide to manufacture liquid aluminum sulfate (Al₂(SO₄)₃), or with iron scrap to produce ferrous sulfate (FeSO₄) used extensively in municipal and industrial wastewater clarification.
2. Alkaline Wastewater Neutralization
Neutralizes highly alkaline wastewater in textile finishing and paper mills. Compared to hydrochloric acid, sulfuric acid introduces sulfate ions rather than chloride ions, minimizing corrosion in concrete bio-reactors.
