Chemical Profile

Product Overview

Hydrochloric Acid 20% Technical Grade is a pre-diluted aqueous solution of hydrochloric acid (HCl) prepared with high-purity deionized water. This 20% concentration provides a convenient, ready-to-use form that eliminates the need for on-site dilution of concentrated stock. Appearance: Clear, colorless to slightly yellow liquid. This Technical Grade product is manufactured for industrial and commercial applications where high purity is required for consistent performance.

Supplied by Alliance Chemical in sizes ranging from 1 quart to 330-gallon IBC totes, this solution is ideal for operations requiring consistent 20% strength with minimal handling risk compared to higher concentrations.

Common Applications

pH Adjustment & Neutralization: Widely used to lower pH in water treatment, chemical processing, and industrial wastewater systems.
Metal Pickling & Cleaning: Removes rust, scale, and oxide layers from steel and iron surfaces prior to coating or galvanizing.
Oil Well Acidizing: Injected into limestone and carbonate formations to increase porosity and stimulate production flow.
Food Processing: Used as a pH regulator in food production, gelatin manufacturing, and corn syrup processing.
Laboratory Analysis: Standard acid for titrations, sample digestion, and reagent preparation in analytical laboratories.

Safety Precautions

Hydrochloric Acid is a strong acid that is corrosive to skin, eyes, and respiratory tract. Releases hydrogen chloride fumes which are irritating. Handle in well-ventilated areas with appropriate PPE. Store in HDPE containers in a cool, dry area separated from bases, metals, and oxidizers.

PPE Requirements: Wear acid-resistant gloves, splash goggles, face shield, and chemical-resistant apron. Use respiratory protection if ventilation is inadequate. In case of contact, flush affected area with large amounts of water. Refer to the Safety Data Sheet (SDS) for complete emergency response procedures.

Shipping: UN 1789, Hydrochloric acid, Class 8, PG II/III (varies by concentration).

Benefits

Pre-Diluted Safety: Lower concentration reduces fume generation and handling risk compared to concentrated HCl.
Reliable Purity: Manufactured with quality-controlled processes for consistent analytical and industrial performance.
Scalable Supply: Available in sizes from quart bottles to IBC totes for any production requirement.
