A hydronium ion is formed when a positively charged hydrogen ion bonds with a molecule of water through a coordinate covalent bond.
Moreover, hydrogen bonds are involved in attracting water molecules to hydronium and hydroxide ions. In both cases three water molecules appear to be rather tightly held, giving formulas H 3 O(H 2 O) 3 + (or H 9 O 4 +) and HO(H 2 O) 3 â (or H 7 O 4 â).ossible structures for the hydrated hydronium and hydroxide ions are shown in Fig. 1. Hydrogen bonding of hydronium and hydroxide ions to water molecules accounts rather nicely for the unusually large electrical currents observed for some electrolytes containing H and OH.
