Acid-Base Titrations | Boundless Chemistry

A strong acid yields a weak conjugate base (A –), so a strong acid is also described as an acid whose conjugate base is a much weaker base than water. Key Terms strong acid : A strong acid is one that completely ionizes (dissociates) in water; in other words, one mole of a strong acid (HA) dissolves in water yielding one mole of H+ and one mole of the conjugate base, A−.

Hypochlorous acid - Wikipedia

Hypochlorous acid (HOCl or HClO) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO−. HClO and ClO− are oxidizers, and the primary disinfection agents of chlorine solutions.[2] HClO cannot be isolated from these solutions due to rapid equilibration with its precursor
