Hydrochloric Acid
Hydrochloric Acid Supplier
Hydrochloric Acid (HCl), also known as muriatic acid, is a strong mineral acid and one of the most fundamental industrial chemicals in the world. Essential for steel pickling, pH control, ore processing, and chemical synthesis, it plays a critical role in manufacturing and infrastructure across virtually every major industry. With more than 75 years of experience as a pioneering innovator, Alexander Chemical supplies top-quality Hydrochloric Acid in liquid form, backed by expert technical guidance and reliable bulk delivery services. Safety and compliance are our top priorities.
Key Characteristics of Hydrochloric Acid
Chemical Properties
- Hydrochloric Acid Formula: HCl
- Appearance: Clear, colorless to slightly yellow liquid
- Odor: Pungent, strongly irritating
- Solubility: Miscible with water in all proportions
- pH: Strongly acidic (pH < 1 at typical concentrations)
- Common Concentration: 31–37% HCl (muriatic/industrial grade)
Storage & Handling Requirements
- Store in rubber-lined or HDPE tanks; avoid metal containers
- Requires ventilation — releases hydrogen chloride fumes
- Keep away from strong bases, oxidizers, and reactive metals
Hydrochloric Acid is a hazardous material. Highly reactive with most metals — contact can produce flammable and explosive hydrogen gas in an exothermic reaction. Fumes are strongly irritating to eyes and respiratory system. Mishandling can lead to serious safety and environmental risks. Always rely on certified professionals for storage, handling, and transportation.
What are the Uses of Hydrochloric Acid?
Hydrochloric Acid is one of the most versatile mineral acids, used across a remarkable breadth of industrial processes wherever a strong, non-oxidizing acid is required.
Steel Pickling & Metal Processing
One of the largest industrial uses of hydrochloric acid is the pickling of steel and iron — removing rust, scale, and oxide coatings from metal surfaces prior to coating, galvanizing, or further processing. It is also widely used in acid cleaning of heat exchangers, boilers, and process equipment.
pH Adjustment & Water Treatment
Hydrochloric acid is used in municipal and industrial water treatment to adjust pH, neutralize alkaline streams, and control scaling. Its high reactivity and clean reaction profile — forming only water and chloride salts — make it a preferred choice for pH control applications.
Chemical Manufacturing
Hydrochloric acid is a key reagent and feedstock in the production of PVC (polyvinyl chloride), chlorinated compounds, pharmaceutical intermediates, dyes, and a wide range of specialty chemicals. It is also essential to the production of chlorides and other inorganic chemicals.
Ore Processing & Mining
In hydrometallurgy and ore processing, hydrochloric acid is used to leach metals from ores, dissolve mineral matrices, and purify metal solutions. It plays an important role in processing rare earth elements and other strategic minerals.
Food-Grade Applications
Food-grade hydrochloric acid is used in the production of glucose syrups, fructose, and other food additives. It is also used as a pH control agent in food and beverage processing and for equipment cleaning and sanitation in food manufacturing facilities.
Other Industrial Applications
- Masonry and concrete cleaning and etching
- Ion exchange resin regeneration
- Leather tanning

A Brief History of Hydrochloric Acid
Hydrochloric acid has one of the longest histories of any industrial chemical. Jabir ibn Hayyan, the 8th-century Arab alchemist, is credited with producing an early form of hydrochloric acid through the reaction of salt and vitriol. European alchemists further refined its production, and by the 16th century it was well known to chemists across the continent. Joseph-Louis Gay-Lussac formally named it ‘hydrochloric acid’ in 1814. Industrial-scale production came with the Leblanc soda ash process in the early 19th century, in which hydrochloric acid was a significant byproduct. The modern chlor-alkali process and direct synthesis from hydrogen and chlorine now dominate production. Today, hydrochloric acid is one of the most important and widely produced mineral acids globally.
Hydrochloric Acid Facts
- Nature’s Acid: Stomach acid is approximately 0.5% hydrochloric acid — the body’s own version, essential for protein digestion and protecting against pathogens. Industrial-grade muriatic acid is many times more concentrated.
- PVC’s Secret Ingredient: Nearly all of the world’s PVC plastic — used in pipes, cables, flooring, and packaging — is produced using processes that depend on hydrochloric acid as a key raw material or byproduct.
- The Masonry Workhorse: Diluted muriatic acid has long been a staple in construction for cleaning brick, etching concrete, and removing mortar stains — one of its most familiar uses outside industrial settings.
- Ancient Alchemy: Jabir ibn Hayyan’s 8th-century production of hydrochloric acid makes it one of the oldest intentionally synthesized chemical substances — predating modern chemistry by over a millennium.
- Steel’s Best Friend: Before steel products can be galvanized, coated, or further processed, they must be pickled clean — and hydrochloric acid is the most widely used pickling agent in the global steel industry.
Frequently Asked Questions about HCl
What is hydrochloric acid?
Hydrochloric acid (HCl), also known as muriatic acid, is a strong mineral acid formed by dissolving hydrogen chloride gas in water. It is typically supplied in concentrations of 31–37% for industrial use and is one of the most widely produced and applied industrial acids in the world.
What is hydrochloric acid used for?
The most common industrial uses of hydrochloric acid are steel pickling, pH adjustment in water treatment, chemical manufacturing (particularly PVC production), ore processing, and food-grade applications including glucose and fructose production. It is also widely used for equipment cleaning and masonry treatment.
What is the difference between hydrochloric acid and muriatic acid?
Muriatic acid is a common commercial name for hydrochloric acid, typically referring to technical-grade or lower-purity versions sold for construction and cleaning purposes. Industrial-grade hydrochloric acid supplied by Alexander Chemical meets strict purity specifications appropriate for demanding applications.
Is hydrochloric acid safe for use in food processing?
Yes. Food-grade hydrochloric acid is approved for use in food processing applications including glucose production, pH adjustment, and equipment sanitation, where permitted by applicable regulations. Alexander Chemical can advise on food-grade specifications and compliance requirements.
How is hydrochloric acid delivered?
Alexander Chemical delivers hydrochloric acid via bulk tankers, intermediate bulk containers (totes), and drums based on your volume and site requirements. All deliveries are handled through Circle Transport, our dedicated logistics partner.
How should hydrochloric acid be stored?
Hydrochloric acid should be stored in rubber-lined or HDPE tanks in a well-ventilated area. Metal containers and fittings must be avoided, as the acid will corrode them and may produce hydrogen gas. Keep away from bases, oxidizers, and reactive metals. Alexander Chemical provides tank inspection and maintenance support as part of our delivery and compliance services.
What industries use hydrochloric acid?
Hydrochloric acid is used across a wide range of industries including steel and metal processing, chemical manufacturing, water and wastewater treatment, food processing, mining and hydrometallurgy, construction, and pharmaceutical production.
