How can chloric acid (HClO3) act as an Arrhenius acid when dissolved in water?

Answer 1

An Arrhenius acid is a substance that produces or generates or donates hydrogen ions when dissolved in water. Thus, HClO₃ + H₂O ==> H₃O⁺ + ClO₃^-

The chloric acid (HClO₃) has donated a proton (H+) to water (H₂O) to produce the hydronium ion (H₃O⁺).
