An Arrhenius acid is a substance that dissociates in water to form hydrogen ions or protons.
<h3>What is an Arrhenius acid?</h3>An Arrhenius acid increases the number of ions in the water.
According to the Arrhenius theory, a substance which has hydrogen atom and can easily give hydrogen ion or proton in its aqueous solution is called as Arrhenius acid.
For example, when hydrochloric acid is dissolved in water, it forms chloride ion () and hydronium ion (
).
