Under Arrhenius theory, which substance produces H+ in water?

Explanation:
Under Arrhenius theory, acids are substances that increase the hydrogen-ion concentration in water by dissociating to release protons. In aqueous solution, those H+ ions are quickly hydrated to form hydronium (H3O+). So the substance that produces H+ in water is an Arrhenius acid. Arrhenius bases, in contrast, produce OH- in water. The Brønsted-Lowry concept is broader and describes proton donation in any solvent, not just water, whereas STP has no relevance to acidity.
