What is a strong acid?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
A strong acid is a substance that completely dissociates (breaks apart) into ions when dissolved in water, releasing all its hydrogen ions (H+). Common examples include hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3). Strong acids have very low pH values (typically 0-1) and are highly corrosive. They conduct electricity well in solution because of the high concentration of ions, and they react vigorously with bases, metals, and other substances.
