Product Overview
Alliance Chemical offers Hydrochloric Acid 5% Technical Grade, a high-quality aqueous solution of hydrogen chloride (ClH) formulated for applications requiring precise, low-concentration acidity. Also known as muriatic acid, this solution is a colorless, watery liquid with a sharp, pungent, and irritating odor. As a versatile industrial acid, it is utilized across diverse operations such as pH adjustment, concrete etching, metal cleaning, and general scale removal. This specific 5% concentration minimizes the hazards associated with high-strength fuming acids while delivering reliable chemical reactivity. We supply this solution to help operations maintain consistent and predictable process conditions without the need for manual, on-site dilution of concentrated acids.
Our technical grade formulation ensures that industrial users receive a dependable product suitable for non-analytical, commercial processes. Distributed directly from our Texas facility, this chemical is managed under strict quality protocols to guarantee consistency across every batch.

For operators seeking a reliable technical grade reagent, this solution provides optimal solubility of 82.3 g/100 g at 32 °F and a density of 1.05 at 59 °F, ensuring easy blending and application in various industrial systems.
Why This Grade
Selecting Technical Grade Hydrochloric Acid 5% is critical for applications where higher purity grades, such as ACS or electronic grade, are cost-prohibitive or unnecessary, yet where the concentration must remain tightly controlled. A 5% concentration provides a mild, manageable acidic environment ideal for delicate scale removal and steel pickling without causing rapid, uncontrolled substrate degradation. Attempting to use a more concentrated variant, such as 31% or 37%, increases the risk of flash rusting, excessive heat generation, and severe outgassing. This pre-diluted 5% version ensures that facilities avoid the inherent safety and consistency issues of manual dilution, which often results in concentration drift and compromised process standards.
Utilizing the incorrect grade or concentration in sensitive operations leads to immediate failure modes. For example, using a lower concentration may fail to completely dissolve carbonate scales, leaving industrial equipment partially blocked and reducing thermodynamic efficiency. Conversely, introducing an over-concentrated acid can cause catastrophic pitting corrosion in industrial piping and storage systems. This technical grade is specifically formulated with a low vapor pressure of 413.6 mmHg and a boiling point of 123 °F to ensure high thermal stability under normal operating conditions.

Industrial Applications
- Industrial equipment descaling and carbonate removal, where the mild acid dissolves calcium deposits from heat exchangers and boiler systems safely.
- Metal surface preparation and pickling, designed to strip mill scale and iron oxides from steel surfaces prior to galvanizing or painting.
- pH control and neutralization protocols in industrial wastewater treatment facilities, ensuring chemical discharges align with municipal and environmental regulatory standards.
- Concrete etching and surface profiling, preparing masonry substrates for high-performance industrial coatings by opening pores to ensure strong adhesion.
- Regeneration of ion-exchange resins in water purification systems, where the acid restores active hydrogen ions to the resin beads efficiently.
Hazmat & Shipping
Hydrochloric Acid 5% Technical Grade is classified as a hazardous material due to its corrosive properties. For transport and logistics purposes, this chemical is regulated under Department of Transportation guidelines as UN1789, Hazard Class 8, Packing Group III. The proper shipping name is Hydrochloric acid. The designated signal word is Danger. Because it is a corrosive liquid, freight and parcel shipping are strictly managed to meet compliance standards. We ship these containers via certified hazmat carriers to guarantee safe handling and lawful transit from our docks to your receiving facility.
Based on the GHS classifications of H314 (causes severe skin burns and eye damage) and H331 (toxic if inhaled), appropriate personal protective equipment (PPE) is strictly mandatory during handling. Operators must wear chemical-resistant gloves, splash-proof goggles, face shields, and protective aprons. In areas with inadequate ventilation, respirators equipped with acid gas cartridges are required to prevent inhalation of the pungent, irritating vapors. GHS pictograms are not applicable as specified in our canonical data for this dilution, but standard corrosive handling protocols must always be enforced.
Handling & Storage
Storage of Hydrochloric Acid 5% Technical Grade requires dedicated chemical containment. Keep containers tightly closed in a cool, dry, well-ventilated area, maintaining temperatures between 50 °F and 85 °F to prevent excessive vapor pressure buildup. Utilize only acid-resistant, high-density polyethylene (HDPE) or glass containers, as this solution is highly corrosive to metals, including steel, copper, and aluminum. Store away from incompatible substances such as strong bases, oxidizing agents, cyanides, sulfides, and active metals. Avoid contact with skin and eyes, and ensure safety showers and eyewash stations are easily accessible in all storage zones.
Order & Documentation
We offer Hydrochloric Acid 5% in multiple packaging options, from individual quarts to multi-gallon cases, to accommodate different industrial scales.
