Separation of Group IIIB Elements from Liquid Media -

2021-10-16 · The Group IIIB elements of scandium, yttrium, and lutetium readily lose their three outer shell electrons to form +3 ions in solution. The aqueous ions of M 3+ are hydrolyzed in water to the common form of [M(OH)(H 2 O) n-1] 2+.The Lanthanide series also forms these same ions so they exhibit similar separation chemistries.
