Tungsten (II) chloride is the inorganic compound with the formula W 6 Cl 12. It is a polymeric cluster compound. The material dissolves in concentrated hydrochloric acid, forming (H 3 O) 2 [W 6 Cl 14 ] (H 2 O) x. Heating this salt gives yellow-brown W 6 Cl 12. [1]
The permissible exposure limit ( PEL or OSHA PEL) is a legal limit in the United States for exposure of an employee to a chemical substance or physical agent such as high level noise. Permissible exposure limits were established by the Occupational Safety and Health Administration (OSHA). Most of OSHA's PELs were issued shortly after adoption ...
Tungsten forms a number of oxyhalides including WOCl 4, WOCl 3, WOCl 2. The corresponding bromides (WOBr 4, WOBr 3, WOBr 2) are also known as is WO 2 I 2. Reactions Structure of the complex WO 2 Cl 2 (dimethoxyethane). WO 2 Cl 2 is a Lewis acid, forming soluble adducts of the type WO 2 Cl 2 L 2, where L is a donor ligand such as bipyridine and ...
