2. I believe the original definition for an Arrhenius base was that a base material contained the OH ion. LiOH would be the answer for this question. I believe the definition was expanded somewhat, later, to include anything that produced an OH ion in aqueous solution. As such, NH3 would qualify because
NH3 + HOH ==> NH4^+ + OH^-
