  • Hydrochloric acid, HCl
  • Sulfuric acid, H2SO4
  • Nitric acid, HNO3
  • Hydrobromic and hydroiodic acid: HBr and HI

Why can concentrated acid be weak acids?

An acid is considered 'weak' or 'strong' regardless of concentration or dilution. An acid's strength is determined by how easily the H+ ions disassociate in an aqueous solution. Strong acids like HCl do this readily, and are considered strong, even when heavily diluted. Organic acids like Citric Acid tend to be 'weak' acids, and are considered 'weak' even when concentrated.


Is bromine a strong or a weak acid?
