Unit 14 pH Acid, Base, Titration Review

In aqueous solution, are all Arrhenius acids also Bronsted-Lowry?

• Yes, because all Arrhenius acids form hydronium ions by donating protons to water.

• Yes, because all Arrhenius acids dissociate completely in aqueous solution.

• No, because some Arrhenius acids form hydrogen ions but do not interact with water.

• No, because some Arrhenius acids do not dissolve in water.
