We see, also, thatcaesium causes inflection, and rubidium does not; and these two metals are allied to sodium and potassium.
Caesium is best detected by the spectroscope, its spectrum being characterised by two lines in the blue and one in the red; the latter is about midway between the lithium and sodium lines.
The precipitate is washed into a beaker, and treated with sulphuretted hydrogen; after filtering off the sulphide of antimony, the solution leaves, on evaporation, the caesium as chloride.
The caesium is precipitated as a white crystalline precipitate (CsCl.
The action of salts of caesium with chloride of antimony might be used as a test for the latter.
A salt of caesium gives a white precipitate with chloride of antimony in concentrated ClH; it contains 30.
Caesium and rubidium salts, even in dilute solutions, are precipitated by it; neutral solutions of ammonium chloride give with it a white precipitate, soluble with difficulty in large quantities of water.
It led Bunsen himself almost immediately to the isolation of two new elements of the alkali group, caesium and rubidium.
Bunsen, the best source of rubidium and caesium salts is the residue left after extraction of lithium salts from lepidolite.
Caesium nitrate, CsNO3, is obtained by dissolving the carbonate in nitric acid, and crystallizes in glittering prisms, which melt readily, and on heating evolve oxygen and leave a residue of caesium nitrite.
The metal has been obtained by electrolysis of a mixture of caesium and barium cyanides (C.
Caesium chloride, CsCl, is obtained by the direct action of chlorine on caesium, or by solution of the hydroxide in hydrochloric acid.
The double chloride ofcaesium and antimony 3CsCl·2SbCl3 (R.
This residue consists of sodium, potassium and lithium chlorides, with small quantities of caesium and rubidium chlorides.
The caesium and rubidium are separated from this by repeated fractional crystallization of their double platinum chlorides, which are much less soluble in water than those of the other alkali metals (R.
The atomic weight of caesium has been determined by the analysis of its chloride and bromide.
The platino-chlorides are reduced by hydrogen, and the caesium and rubidium chlorides extracted by water.
The spectroscopic test, however, failed to show caesiumin the ashed plant.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "caesium" in a variety of sentences. We hope that you will now be able to make sentences using this word.
