A hydronium ion is formed when a positively charged hydrogen ion bonds with a molecule of water through a coordinate covalent bond.
Hydronium ion is a water molecule with an extra hydrogen ion attached to it. (H2O + H+ â H3O+). It usually used to determine the acidity of a chemical compound. When a compound is put into water solution, the more the hydronium ion is produced, the higher the acidity is.The Hydrogen ion is transferred to water molecule. A hydronium ion can also be represented as just a hydrogen ion (H+) in place of H3O+.he hydronium ion is a polyatomic ion that forms when an acid releases a proton (H+) to a water molecule.
