WebOsmium tetroxide is the chemical compound with the formula OsO4. The compound is noteworthy for its many uses, despite the rarity of osmium. Pure OsO 4 is colorless and volatile; it has a characteristic acrid chlorine-like odor and is soluble in a wide range of organic solvents. WebThis oxysulphide of osmium is soluble in acids with decomposition, even sulphuric acid it with evolution of sulphureted hydrogen. It possesses acid properties, for it liberates … OsO 4 is very soluble in tert-butyl alcohol. In solution, it is readily reduced by hydrogen to osmium metal. The suspended osmium metal can be used to catalyze hydrogenation of a wide variety of organic chemicals containing double or triple bonds.
