Reaction of actinum with airActinium metal rapidly oxidizes to actinium (III) oxide, Ac2O3 in moist air [4].
4 Ac(s) + 3 O2(g) 2 Ac2O3(s) Reaction of actinum with carbonateAc3+ is precipitated by carbonate ions [4].
2 Ac3+(aq) + 3 CO32−(aq) Ac2(CO3)3(s) Reaction of actinum with oxalateAc3+ is precipitated by oxalate ions [4].
2 Ac3+(aq) + 3 C2O42−(aq) Ac2(C2O4)3(s) Reaction of actinum with phosphateAc3+ is precipitated by phosphate ions [4].
