Selenium trioxide with water
WebPreparation. Selenium trioxide is difficult to prepare because it is unstable with respect to the dioxide: 2 SeO 3 → 2 SeO 2 + O 2. It has been generated in a number of ways despite the fact that the dioxide does not combust under normal conditions. One method entails dehydration of anhydrous selenic acid with phosphorus pentoxide at 150–160 °C. Another … WebAug 15, 2024 · Selenium forms hydrogen selenide, H 2 Se, a colorless flammable gas when reacted with hydrogen. Reaction with oxygen Selenium burns in air displaying a blue flame and forms solid selenium dioxide. (1) S e 8 ( s) + 8 O 2 ( g) → 8 S e O 2 ( s) Selenium is also known to form selenium trioxide, SeO 3. Reaction with halides

WebSELENIUM TRIOXIDE ICSC: 0949 ENVIRONMENTAL DATA NOTES The substance may have effects on the liver, kidneys and spleen, resulting in organ lesions. Nasopharyngeal irritation, gastrointestinal distress and persistent garlic odour may occur. Solid SeO2 is a one-dimensional polymer, the chain consisting of alternating selenium and oxygen atoms. Each Se atom is pyramidal and bears a terminal oxide group. The bridging Se-O bond lengths are 179 pm and the terminal Se-O distance is 162 pm. The relative stereochemistry at Se alternates along the polymer chain (syndiotactic). In the gas phase selenium dioxide is present as dimers and other oligomeric species, at higher temperatures it is monomeric. The monomeric fo…
