Why is aluminum considered an acid cation? - Al3+ ions bind with water to create alumic acid, which lowers pH - Al3+ ions have a large hydrated radius which prevent basic cations from binding to the colloidal surface -Al3+ ions have a strong tendency to hydrolyze, which released H+ ions -Al3+ ions are part of lime, which is acidic
