Define an Arrhenius acid and describe properties of acids. Use an example to explain how an Arrhenius acid will behave when dissolved in water.

An Arrhenius acid is a substance that dissociates in water to form hydrogen ions or protons. In other words, it increases the number of H+ ions in the water. In contrast, an Arrhenius base dissociates in water to form hydroxide ions, OH-.

Arrhenius Acid Definition 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 (Cl –) and hydronium ion (H 3 O +).

Explanation:

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
