Answer:
According to the theory, an Arrhenius acid is a substance that gives hydrogen ion, [tex]H^{+}[/tex] (or protons) as the only positively charged ions, when dissociated in water.
Explanation:
What this means is that acids increase the concentration of protons in water to form hydronium ions,as opposed to the idea that there aren't free hydrogen cations floating around in aqueous solution.
The Arrhenius definitions of acidity and alkalinity are restricted to aqueous solutions and refer to the concentration of dissolved ions.
