Carbon monoxide combines with fluorine on heating to form carbonyl fluoride: CO + F 2 = COF 2. Metallic hydroxides react with fluorine to form a metallic fluoride and oxygen; for example, 2Ba(OH) 2 + 2F 2 = 2BaF 2 + 2H 2 O + O 2. Aqueous solutions of NaOH and KOH interact with fluorine at 0°C to yield OF 2.
