Sulfuric acid (alternative spelling sulphuric acid) is a highly corrosive strong mineralacid with the molecular formula H2SO4. It is a pungent-ethereal, colorless to slightlyyellow viscous liquid which is soluble in water at all concentrations.[6] Sometimes, it isdyed dark brown during production to alert people to its hazards.[7] The historical nameof this acid is oil of vitriol.[8]

Sulfuric acid is a diprotic acid and shows different properties depending upon itsconcentration. Its corrosiveness on other materials, like metals, living tissues oreven stones, can be mainly ascribed to its strong acidic nature and, ifconcentrated, strong dehydratingand oxidizing properties. Sulfuric acid at ahigh concentration can cause very serious damage upon contact, since not only does itcause chemical burns via hydrolysis, but also secondary thermalburns through dehydration.[9][10] It can lead to permanent blindnessif splashedonto eyes and irreversible damage if swallowed.[9] Accordingly, safety precautionsshould be strictly observed when handling it. Moreover, it is hygroscopic, readilyabsorbing water vapour from the air.[6]

Sulfuric acid has a wide range of applications including domestic acidic draincleaner,[11] electrolyte in lead-acid batteries and variouscleaning agents. It is also acentral substance in the chemical industry. Principal uses include mineralprocessing, fertilizermanufacturing, oil refining, wastewater processing, and chemicalsynthesis. It is widely produced with different methods, such ascontact process, wetsulfuric acid process and some other methods.
