Sulfuric Acid 96% ACS Grade

Product Overview

Sulfuric Acid 96% ACS Grade (H₂SO₄), historically known as Oil of Vitriol, is a strong mineral acid utilized across industrial and laboratory sectors. This ACS-grade solution ensures high purity with strictly controlled impurities (Heavy Metals ≤ 0.2 ppm, Chloride ≤ 0.5 ppm), making it suitable for analytical protocols where standard technical grades may introduce interference. With a typical assay range of 96–99.5 wt%, it functions as a reliable dehydrating agent, pH adjuster, and catalyst.

Alliance Chemical supplies this high-density liquid (approx. 1.84 g/mL) for demanding applications including chemical synthesis, metal processing, and wastewater treatment. The product meets ACS Reagent Grade specifications, ensuring consistency for quality-control environments. It is packaged in corrosion-resistant, UN-rated containers to maintain stability during transport and storage.

Safety Precautions

DANGER: Sulfuric Acid 96% is extremely corrosive and causes severe skin burns and eye damage. It is a strong oxidizer and reacts violently with water.

• PPE: Wear chemical-resistant gloves, apron/coveralls, and splash-proof chemical goggles/face shield.
• Handling: Always add acid to water (never water to acid) to prevent violent boiling and splashing. Use in a well-ventilated area or fume hood.
• Storage: Store in a cool, dry place in corrosion-resistant containers (HDPE, glass). Keep away from incompatible materials such as bases, combustibles, and reducing agents.
• Shipping: UN 1830, Sulfuric Acid, Class 8, PG II.
