A hydronium ion is formed when a positively charged hydrogen ion bonds with a molecule of water through a coordinate covalent bond.
The Hydrogen ion H+ consists of a hydrogen atom missing an electron, in other words its a proton. In water it occurs as the hydronium ion (H3O+) and in higher concentrations m â¦ akes a solution acidic. The Hydroxide ion OH-consists of a hydrogen ion covalently bonded to an oxygen atom that has an extra electron.It makes and aqueous solution basic or alkaline.hen any pure metal from Group 1 of the periodic table comes into contact with water, the water, which is H2O, is torn apart in the reaction, and two things will happen. First hydrogen gas will be liberated, and second, OH ions (hydroxide ions) will be formed when they combine with the metal.
