The hydronium ion is a polyatomic ion that forms when an acid releases a proton (H+) to a water molecule.he hydronium ion is a polyatomic ion that forms when an acid releases a proton (H+) to a water molecule.
This special case of water reacting with water to produce hydronium (and hydroxide) ions is commonly known as the self-ionization of water. The resulting hydronium ions are few and short-lived. pH is a measure of the relative activity of hydronium and hydroxide ions in aqueous solutions.In acidic solutions, hydronium is the more active, its excess proton being readily available for reaction with basic species.ydronium is very acidic: at 25 Â°C, its pKa is â1.7. It is also the most acidic species that can exist in water (assuming sufficient water for dissolution): any stronger acid will ionize and protonate a water molecule to form hydronium.
