What does sulfuric mean?
Sulfuric is an adjective used chiefly in the term sulfuric acid, the common name for H₂SO₄, a highly corrosive mineral acid. It may also describe other substances or phenomena associated with sulfuric acid, but nearly all modern usage involves the established compound. The adjective should not be confused with sulfur, which names the chemical element from which the acid is made. American English normally uses sulfuric, while British English commonly uses the alternative spelling sulphuric. In laboratory and industrial contexts, dilute sulfuric acid is safer to handle than the concentrated form, which is strongly hygroscopic, corrosive, and capable of causing severe burns. The word is consequently associated with chemistry, batteries, metal processing, fertilizer production, and laboratory safety.
adjectiveOf, relating to, or containing sulfuric acid, a strong corrosive acid with the chemical formula H₂SO₄.
- Relating to or containing sulfuric acid.
"The technician handled the concentrated sulfuric acid with extreme care."
"Dilute sulfuric acid was used to prepare the solution for testing."
"The battery uses sulfuric acid as its electrolyte."
Before its modern chemical name, sulfuric acid was famously sold as oil of vitriol, an ominous name for one of the most corrosive substances in the laboratory.

Where does sulfuric come from?
Sulfuric was formed in English from sulfur with the suffix -ic, a combining form associated with chemical names and characteristic acid-forming compounds. It developed alongside the growing systematic nomenclature of chemistry in the late eighteenth century. The related word sulfur comes through Latin from an earlier form meaning the yellow substance later identified as brimstone. The British spelling sulphuric reflects the established British convention of retaining the spelling -ph- in sulfur-related words.
How sulfuric is actually used
In current English, sulfuric is overwhelmingly used in the established compound sulfuric acid. British English traditionally spells it sulphuric, although both spellings are understood internationally.
