What is a strong acid?

A strong acid is a type of acid that completely ionizes or dissociates into its ions in a solution. This means that it donates all its hydrogen ions (H+) when dissolved in water. Examples of strong acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3). The strength of an acid is determined by its acid dissociation constant (Ka), with a larger Ka indicating a stronger acid. Strong acids are also characterized by their ability to neutralize bases, turn blue litmus paper red, and conduct electricity in solution due to the presence of ions.
