Fumes are seen when barium halides are kept in open air due to their reaction with moisture and carbon dioxide present in the atmosphere. Barium halides can absorb water, leading to hydrolysis and the formation of barium hydroxide and corresponding acids. Additionally, exposure to carbon dioxide can result in the formation of barium carbonate, which may also produce visible fumes. This interaction creates an observable mist or haze around the barium halides.

Why does an open gasoline can fill the garage with the smell of gas?

How much can you heat brass before toxic fumes?
Brass typically begins to release harmful fumes when heated above approximately 400°F (204°C), especially if it contains higher levels of zinc, which can produce zinc oxide fumes. Prolonged exposure to temperatures above this threshold can lead to significant fume release, particularly when the brass is exposed to open flames or extreme heat. It is important to ensure proper ventilation and safety precautions when heating brass to avoid inhaling toxic fumes. Always consult relevant safety guidelines when working with metals.
