Osmium(I) iodide is a metallic grey solid produced by the reaction of osmium tetroxide and hydroiodic acid heated in a water bath for 48 hours in a carbon dioxide atmosphere. It is an amorphous compound. [34] Osmium(II) iodide is a black solid [35] produced by the reaction of osmium tetroxide and hydroiodic acid at 250 °C in nitrogen: [34]
This toxic compound is formed when powdered osmium is exposed to air. It is a very volatile, water-soluble, pale yellow, crystalline solid with a strong smell. Osmium powder has the characteristic smell of osmium tetroxide. [31] Osmium tetroxide forms red osmates OsO 4 (OH) 2− 2 upon reaction with a base.
An air flow meter is a device similar to an anemometer that measures air flow, i.e. how much air is flowing through a tube. It does not measure the volume of the air passing through the tube, it measures the mass of air flowing through the device per unit time, though Thus air flow meters are simply an application of mass flow meters for the ...

Osmium (II) chloride or ... chloride is a hygroscopic dark brown solid that is insoluble in water. [3] ... Osmium(II) chloride does not react with hydrochloric acid ...
This depth is converted to a flow rate according to a theoretical formula of the form = where is the flow rate, is a constant, is the water level, and is an exponent which varies with the device used; or it is converted according to empirically derived level/flow data points (a "flow curve"). The flow rate can then be integrated over time into ...

Osmium(III) chloride hydrate is used as a precursor material for the production of dichlorodihydridoosmium complex compounds and other compounds. [ 5 ] It is the precursor to a variety of arene complexes.
