Final answer:
H2SO4 (aq) is both an Arrhenius acid and a Brønsted-Lowry acid, as it can release H+ ions in water and donate a proton.
Step-by-step explanation:
H2SO4 (aq) is both an Arrhenius acid and a Brønsted-Lowry acid. According to the Arrhenius definition, an acid produces H+ ions in solution, and H2SO4 can release H+ ions in water. Similarly, according to the Brønsted-Lowry definition, an acid is a proton (H+) donor, and H2SO4 can donate a proton.
Therefore, H2SO4 (aq) fits the criteria for both these acid classifications.
