Sulfuric Acid 30%

Product Overview

Sulfuric Acid 30% is a highly concentrated aqueous solution of sulfuric acid (H₂SO₄) designed for rigorous industrial and laboratory applications. The product is supplied with ACS Reagent Grade and USP-NF Monograph compliance, ensuring high purity and consistent performance across batches. Its 30% w/w acidity provides strong catalytic and dehydrating capabilities while maintaining manageable handling characteristics for process systems requiring precise acidification and water redistribution. The solution presents as a clear, colorless to pale yellow liquid with odorless properties, and is formulated to balance reactivity with safety in controlled environments. Typical density at 25°C is 1.06 g/mL and the material exhibits a specific gravity around 1.11 at 20°C, enabling accurate process design and dosing in aqueous media. The product is compatible with standard HDPE and glass storage containers and is stabilized to minimize impurities that could affect sensitive downstream processes.

With broad applicability in chemical synthesis, pH control, dehydration steps, and energy storage systems, Sulfuric Acid 30% serves as a reliable reagent for industries ranging from water treatment to pharmaceuticals. Its purification profile emphasizes low trace metal content (e.g., limited chloride, limited arsenic, and controlled heavy metals), making it suitable for applications that demand strict impurity control. The solution’s physical and chemical properties support predictable performance in dehydration reactions, electrolyte formulations for lead-acid batteries, and as a catalyst medium in selected organic transformations.

Safety Precautions

Handling and storage should follow strict chemical hygiene practices. Store in a cool, dry, well-ventilated area away from incompatibles such as strong bases and organic materials. Use compatible container materials (HDPE or glass) and ensure containers remain tightly closed to minimize moisture uptake. PPE should include chemical-resistant gloves, splash-resistant goggles, and chemically resistant protective apparel. Implement engineering controls such as fume hoods or local exhaust in areas of transfer and handling to minimize exposure risk.

In case of a spill or accidental exposure, follow emergency procedures per the SDS: immediately evacuate nonessential personnel, contain the spill with appropriate inert absorbents, and avoid generating aerosols. For exposure, seek first aid per the SDS guidance: eye exposure requires prolonged flushing with water; skin exposure should be rinsed with copious water and contaminated clothing removed. Inhalation and ingestion incidents require immediate medical attention. Transport under UN 1830, Sulfuric acid, Class 8, PG II, with proper labeling and segregation in accordance with applicable regulations.
