Reaction of Aqueous

Are 2+ ions or 3+ ions more acidic in solutions? Why?
3+ ions. 3+ ions are smaller and more highly charged, so have a higher charge density. They attract the electrons from the oxygen of the ligands much more strongly. This weakens the O-H bonds so complex readily a H+ ion into the sol making it acidic.
