tetroxide's Usage Examples:

It is a pale yellow powder (of specific gravity 6.5), which on being heated strongly gives up oxygen and forms the tetroxide.

There are three known oxides of antimony, the trioxide Sb406 which is capable of combining with both acids and bases to form salts, the tetroxide Sb204 and the pentoxide Sb205.

The tetrasulphide, OsS4, is similarly prepared when sulphuretted hydrogen is passed into acid solutions of the tetroxide.

The trichloride, OsC1 3, is only known in solution and is formed by the reducing action of mercury on ammoniacal solutions of the tetroxide.

The tetroxide, 0s04, is formed when osmium compounds are heated in air, or with aqua regia, or fused with caustic alkali and nitre.

The sesquioxide, Os203, results on heating osmium with an excess of the tetroxide.

The barium salt is extracted by water and boiled with nitric acid, when the osmium volatilizes in the form of its tetroxide.

It is also formed by oxidizing bismuth trioxide suspended in caustic potash with chlorine, the pentoxide being formed simultaneously; oxidation and potassium ferricyanide simply gives the tetroxide (Hauser and Vanino, Zeit.

Potassium osmiate, K 2 0sO 4 2H 2 0, formed when an alkaline solution of the tetroxide is decomposed by alcohol, or by potassium nitrite, crystallizes in red octahedra.

On strongly heating in air it is converted into the tetroxide.
