Caesium arsenate

Caesium Arsenate.—By adding excess of arsenic to a solution of caesium hydroxide in nitric acid containing a little molybdic acid, white well-defined crystals of composition Cs20.2As205.5H20 have been obtained.4... [Pg.197]

In the trace analysis of rubidium- and caesium arsenates, arsenic is distilled off as arsine [116]. In the trace analysis of high purity cadmium, the matrix can be separated by distillation at 630 C [117. By heating aluminium with ethyl bromide the metal is converted into ethylaluminium bromide, a liquid which boils at I30 C under reduced pressure [118]. [Pg.18]

The electrical conductivities of soln. of a great many compounds in liquid hydrogen halides have been measured by E. H. Archibald and D. McIntosh. The conductivity is raised considerably by phosphoryl chloride. Sodium sodium sulphide, borate, phosphate, nitrate, thiosulphate, and arsenate chromic anhydride potassium nitrate, hydroxide, chromate, sulphide, bisulphate, and ferro- and ferri- cyanide ammonium fluoride and carbonate j rubidium and caesium chloride magnesium sulphate calcium fluoride ... [Pg.179]

Arsenic, copper, antimony, chromium, mercury, selenium and zinc were concentrated in the precipitate upon storage of acidified urine for 2 days, whereas manganese, cobalt, caesium and rubidium remained in the supernatant fraction (Cornelis et al., 1975). [Pg.7]

Bunsen, Robert Wilhelm (1811-99) German chemist, who held professorships at Kassel, Marburg, and Heidelberg. His early researches on arsenic-containing compounds cost him an eye in an explosion. He then turned to gas analysis and spectroscopy, enabling him and Kirchhoff to discover the elements caesium (1860) and rubidium (1861). He also popularized the use of the Bunsen burner. [Pg.117]

There are 21 elements that show just one single isotope. They include sodium, cesium, beryllium, aluminum, phosphorus, arsenic, bismuth, fluorine, iodine, manganese, cobalt, and gold. Also see note 36. (Throughout this book I use the American spelling for the elements whose symbols are A1 and Cs rather than the official lUPAC spelling of aluminium and caesium.)... [Pg.299]
