What is Strong Acid?
An acid that completely dissociates into ions in aqueous solution. Examples include HCl, HBr, HI, HNO₃, H₂SO₄, and HClO₄. In dilute solutions, virtually no undissociated acid molecules remain. The conjugate base of a strong acid is a very weak base.

Strong acids are used in industrial processes including metal cleaning (pickling), fertiliser production (H₂SO₄ in superphosphate), and chemical synthesis. They are used in analytical chemistry for standardised titrations. Hydrochloric acid is used in food processing and pharmaceuticals.
Strong acids are highly corrosive and cause severe burns to skin, eyes, and mucous membranes. They must be stored in appropriate containers, handled with personal protective equipment, and diluted carefully by adding acid to water, never the reverse.
