Sulfuric Acid 30%

Product Overview

Sulfuric Acid 30% is a Technical Grade aqueous solution of sulfuric acid (H₂SO₄) formulated for industrial manufacturing, water treatment, and laboratory applications. Often referred to by the synonym Oil of Vitriol or Battery Acid in specific contexts, this strong mineral acid acts as a potent pH adjuster and dehydrating agent.

The 30% concentration balances reactivity with handling requirements, making it an ideal choice for process systems requiring precise acidification without the extreme hazards of highly concentrated oleum. This clear, colorless to pale yellow liquid is widely used in metal finishing, chemical synthesis, and neutralization processes. Alliance Chemical supplies this product in high-density polyethylene (HDPE) containers ranging from quarts to bulk totes, ensuring compatibility and safety for industrial users.
