Chemical Properties of Barium

Chemical Properties of Barium. Barium may be kept unchanged in dry carbon dioxide, but readily tarnishes in the air owing to the formation of the oxide and nitride. If in the form of powder it may even take fire. It decomposes both water and alcohol, liberating hydrogen, but is unattacked by dry benzene, toluene, and petrol. It combines with ammonia and also with hydrogen. Its behaviour to ...
