Why a lone proton cannot exist in a glass of water
In short: In chemistry, the hydrogen ion is rarely found alone. This video explains the behavior of the hydronium ion, exploring how protons interact with water molecules to define the acidity of our world.
The hydronium ion (H3O+) is essentially a hydrogen ion that has become hydrated. While a hydrogen ion is technically just a single proton, it is too unstable to exist by itself in an aqueous solution.
Instead, it quickly attaches to a water molecule. The concentration of these ions serves as the primary measure of acidity: the more hydronium ions present, the lower the pH and the more acidic the solution becomes. Understanding this transition from a bare proton to a hydronium ion is fundamental to the Brønsted–Lowry definition of acids and bases.
