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.
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. The hydronium ion is very acidic: at 25 Â°C, its pK a is 0. It is 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.
