Formation of Cadmium Oxide

2Cd + O2 → 2CdO

Descripción general

Cadmium burns in oxygen with a brownish-red tint to form cadmium oxide. This reaction is significant because cadmium and its oxide are highly toxic. Cadmium oxide fumes from welding or smelting operations can cause severe and potentially fatal cadmium poisoning.
