Sulfuric Acid (H₂SO₄), often called the ‘king of chemicals,’ is the most produced industrial chemical on Earth. Its unmatched versatility as a strong acid, dehydrating agent, and catalyst makes it essential to fertilizer production, petroleum refining, metal processing, battery manufacturing, and the synthesis of a vast range of industrial chemicals. With more than 75 years of experience as a pioneering innovator, Alexander Chemical supplies top-quality Sulfuric Acid in liquid form, backed by expert technical guidance and reliable bulk delivery services. Safety and compliance are our top priorities.
Key Characteristics of Sulfuric Acid
Chemical Properties
- Sulfuric Acid Formula: H₂SO₄
- Appearance: Clear, colorless, oily liquid
- Odor: Odorless when pure/cold; acrid when warm or fuming
- Solubility: Miscible with water in all proportions (highly exothermic)
- pH: Strongly acidic (pH < 1 at typical concentrations)
- Common Concentrations: 93–98% (concentrated industrial grade); various dilute grades
Storage & Handling Requirements
- Store in carbon steel, stainless steel, or HDPE tanks depending on concentration
- Always add acid slowly to water — never add water to concentrated acid
- Keep away from organics, combustibles, strong bases, and reactive metals
Sulfuric Acid is a hazardous material. Extremely exothermic when diluted with water — always add acid to water, never reverse. Severely corrosive to skin, eyes, and most materials. Concentrated forms are strongly dehydrating and can cause ignition or charring of organics on contact. Mishandling can lead to serious safety and environmental risks. Always rely on certified professionals for storage, handling, and transportation.
What are the Uses of Sulfuric Acid?
Sulfuric Acid is used in more industrial processes than any other chemical — earning its title as the ‘king of chemicals’ through its sheer versatility and the scale of its global production and consumption.
Fertilizer Production
The largest application of sulfuric acid — accounting for the majority of global consumption — is the production of phosphate and nitrogen fertilizers. Sulfuric acid reacts with phosphate rock to produce phosphoric acid and superphosphates, which are primary inputs to the global phosphate fertilizer industry. It also reacts with ammonia to produce ammonium sulfate fertilizer.
Petroleum Refining
Sulfuric acid is used extensively in petroleum refining as a catalyst in alkylation processes, producing the high-octane blending components used in gasoline. It is also used for treating crude oil fractions, removing impurities, and in the production of various petrochemicals.
Metal Processing & Pickling
Sulfuric acid is used for pickling steel and other metals — removing oxide scale and rust prior to further processing, coating, or galvanizing. It is also used in copper and zinc refining, electroplating, and other hydrometallurgical processes.
Battery Manufacturing
Dilute sulfuric acid (battery acid) is the electrolyte in lead-acid batteries — the most widely used rechargeable battery technology globally, found in automobiles, industrial equipment, and uninterruptible power supply (UPS) systems.
Chemical Synthesis
As a fundamental industrial reagent, sulfuric acid is used in the synthesis of hydrochloric acid, nitric acid, phosphoric acid, dyes, detergents, pharmaceuticals, and a vast range of organic and inorganic chemicals. It is a key component in the Ostwald process for nitric acid production.

A Brief History of Sulfuric Acid
Sulfuric acid has been known since at least the 8th century, when Arab alchemists produced it by distilling iron sulfate (green vitriol) and called it ‘oil of vitriol.’ European alchemists refined its production, and by the 17th century it was used in laboratories and small chemical processes. The first large-scale industrial production came with the lead chamber process, developed in the 1740s. A breakthrough arrived in 1831 when Peregrine Phillips developed the contact process — catalytic oxidation of sulfur dioxide to sulfur trioxide, which is then absorbed to form sulfuric acid. The contact process remains the dominant production method today, capable of producing sulfuric acid at over 98% concentration. Global production now exceeds 300 million tonnes annually, making sulfuric acid by far the most produced industrial chemical on Earth, a distinction it has held for well over a century.
Sulfuric Acid Facts
- King of Chemicals: Sulfuric acid is the most produced industrial chemical on Earth — with annual global output exceeding 300 million tonnes, it outpaces every other chemical by a wide margin, a title it has held for over a century.
- Instant Sugar Charring: Concentrated sulfuric acid is so powerfully dehydrating that it instantly chars sugar — stripping hydrogen and oxygen atoms to leave behind a column of pure black carbon. A dramatic and frequently demonstrated illustration of its dehydrating power.
- Battery Backbone: The lead-acid battery — powering virtually every automobile starter motor and countless industrial backup systems — relies on dilute sulfuric acid as its electrolyte. Without it, modern transportation and power infrastructure would not function.
- Oil of Vitriol: Arab alchemists in the 8th century called it ‘oil of vitriol’ — a name that persisted for over a thousand years and is still occasionally used, reflecting sulfuric acid’s ancient roots in human chemistry.
- Fertilizer Foundation: The majority of global sulfuric acid production goes into making phosphate fertilizers — the chemistry that agriculture depends on to feed a global population of over 8 billion people.
Frequently Asked Questions about H₂SO₄
What is sulfuric acid?
Sulfuric acid (H₂SO₄), also known as oil of vitriol, is a strong diprotic mineral acid and one of the most important industrial chemicals in the world. It is typically supplied as a concentrated aqueous solution (93–98%) or in dilute grades for specific applications, and is produced via the contact process.
What is sulfuric acid used for?
Sulfuric acid’s largest use is in the production of phosphate and nitrogen fertilizers. It is also essential for petroleum refining (alkylation), steel and metal pickling, lead-acid battery electrolyte, chemical synthesis (including production of hydrochloric, nitric, and phosphoric acids), and the manufacture of dyes, detergents, and pharmaceuticals.
Why is sulfuric acid called the king of chemicals?
Sulfuric acid is called the ‘king of chemicals’ because it is the most produced industrial chemical on Earth — with over 300 million tonnes manufactured annually — and because it is used directly or indirectly in the production of a wider range of products than virtually any other chemical.
Why is it dangerous to add water to sulfuric acid?
Adding water to concentrated sulfuric acid causes a violent exothermic reaction that can instantly boil the water and splatter dangerously hot acid. The correct procedure is always to add sulfuric acid slowly to water — never the reverse. This rule applies whenever sulfuric acid is diluted or mixed.
How is sulfuric acid delivered?
Alexander Chemical delivers sulfuric 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 sulfuric acid be stored?
Storage requirements depend on concentration. Concentrated grades are commonly stored in carbon steel tanks, while dilute grades require stainless steel or HDPE. All storage must be kept away from organics, combustibles, bases, and reactive metals. Alexander Chemical provides tank inspection and maintenance support as part of our delivery and compliance services.
What industries use sulfuric acid?
Sulfuric acid is used across virtually every major industrial sector including fertilizer and agricultural chemical production, petroleum refining, steel and metal processing, battery manufacturing, chemical synthesis, mining and metallurgy, and pharmaceutical production.
