the difference between hydrogen ions and hydroxide ions
What is the difference in hydrogen ions and hydroxide ions? 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 mâ¦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.
