Hydrochloric Acid 5% Technical Grade

Product Overview

Hydrochloric Acid 5% Technical Grade is a clear, colorless aqueous solution of Hydrogen Chloride (HCl). Also known as Muriatic Acid or Spirits of Salt, this 5% dilution provides a manageable level of acidity for industrial applications requiring precise pH control without the extreme volatility of higher concentrations. It is formulated to deliver reliable performance in water treatment, metal surface preparation, and general chemical manufacturing.

This Technical Grade solution is manufactured to strict specifications, ensuring low trace metals and consistent assay (4.8–5.2 wt%). It is fully soluble in water and compatible with standard corrosion-resistant dosing systems. Industrial buyers rely on this product for its predictable buffering dynamics in process streams and its utility in neutralizing alkaline waste.

Common Applications

• Water Treatment: Used for pH adjustment (reduction) in industrial wastewater and process water streams to neutralize high alkalinity.
• Metal Processing: Acts as a pickling agent to remove rust, scale, and oxides from steel and iron surfaces prior to coating or plating.
• Masonry & Concrete: Effective for cleaning brick, etching concrete, and removing mortar smears (Spirits of Salt).
• Chemical Synthesis: Serves as a reagent in the production of chlorides, fertilizers, and dyes where controlled acidity is required.
• Laboratory Use: Utilized in titrations and analytical protocols requiring a dilute acid standard.

Safety Precautions

Hydrochloric Acid is corrosive. Handle and store in accordance with the Safety Data Sheet (SDS). Storage areas should be cool, dry, and well-ventilated, using corrosion-resistant containers such as HDPE or glass. Keep away from incompatible materials, specifically strong bases, oxidizers, and metals that may react to release hydrogen gas.

PPE Requirements: Wear chemical-resistant gloves, splash goggles, and protective clothing. Ensure an eyewash station and safety shower are accessible. In the event of exposure, rinse affected area immediately with copious amounts of water and seek medical attention.
