Hydrochloric Acid 15% Technical Grade

Product Overview

Hydrochloric Acid 15% Technical Grade is a clear, colorless solution of hydrogen chloride (HCl) in water. This technical-grade acid provides strong acidic performance with broad reactivity across metal, mineral, and organic substrates. The solution is formulated to deliver consistent acidity control in process streams, with attention to trace impurity limits that support reliable downstream operations. Typical assay ranges (14.5–15.5% w/w, with a 15.0% w/w target) are achieved via standardized acid-base titration against NaOH, ensuring accurate pH adjustment and compatibility with common industrial systems. The product’s density, refractive index, and viscosity are characterized to support precise dosing and metering in automated processes, while controlled impurity levels minimize corrosion risk to contact materials when used within approved systems.

In addition to pH and corrosion control, this solution serves as a versatile reagent in chemical synthesis, water treatment, and analytical workflows where a strong, predictable acid source is required. The Technical Grade designation reflects suitability for industrial and research settings that tolerate trace inorganic impurities typical of acid-base neutralization and cleaning operations. Users should implement appropriate corrosion control strategies and verify compatibility with materials of construction, as HCl is corrosive to many metals and alloys.

Safety Precautions

Proper handling and storage of Hydrochloric Acid 15% Technical Grade are essential to minimize exposure and equipment corrosion. Store in corrosion-resistant containers (e.g., HDPE or glass) in a cool, dry, well-ventilated area away from incompatible materials and bases. Use appropriate PPE, including chemical-resistant gloves, splash goggles, and protective apparel. Ensure that storage areas are equipped with containment measures to manage spills and that incompatible metals and materials are kept separate to prevent unwanted reactions. Follow local regulations and the SDS guidance for safe handling and emergency response.

In case of exposure, follow established emergency procedures: for skin or eye contact, rinse immediately with copious water for at least 15 minutes and seek medical attention; for inhalation, move to fresh air and seek medical evaluation if symptoms persist; for ingestion, do not induce vomiting and seek urgent medical care. The product is designated with the signal word DANGER and contains hazards including skin corrosion, eye damage, metal corrosion, and potential respiratory irritation; ensure proper ventilation and corrosion-control practices during use. Transport is classified as UN 1789, Hydrochloric acid, Class 8, PG II.
