Caesium chlorate

Taking francium as an example, it was assumed that the minute traces of francium ion Fr could be separated from other ions in solution by co-precipitation with insoluble caesium chlorate (VII) (perchlorate) because francium lies next to caesium in Group lA. This assumption proved to be correct and francium was separated by this method. Similarly, separation of astatine as the astatide ion At was achieved by co-precipitation on silver iodide because silver astatide AgAt was also expected to be insoluble. 

Caesium chlorate, CsC103.—The chlorate has been little investigated.4... 

Uses Of the Stassfurt salts.—The magnesium compounds in the Stassfurt salts are used for the preparation of magnesium and of its salts. The potash salts are an essential constituent of many fertilizers used in agriculture, etc. 22 and potassium chloride is the starting-point for the manufacture of the many different kinds of potassium salts used in commerce—carbonate, hydroxide, nitrate, chlorate, chromate, alum, ferrocyanide, cyanide, iodide, bromide, etc. Chlorine and bromine are extracted by electrolysis and other processes from the mother liquids obtained in the purification of the potash salts. Boric acid and borax are prepared from boracite. Caesium and rubidium are recovered from the crude carnallite and sylvite. 

V. 1 Olivier a trace of iodine. L. Dieulafait found traces of lithium, rubidium, and caesium salt H. Beckurts, chlorates and perchlorates up to 5 64 per cent. M. Marcker, borates and humus C. F. Schfinbein, nitrites and ammonia R. Wagner, iodine and bromine. H. Griineberg says the former is present as iodate or periodate. 

Heating samples of this or the corresponding chlorine compounds, leads to explosions if contaminated with caesium bromate or chlorate, which are byproducts of the syntheses. 

In contrast to the p-block elements reported so far, there has been a considerable amount of work carried out with the halogens. In this area there have also been more studies on the radiolysis of various species, an aspect which should be considered in more detail when interpreting the results of recoil experiments. However, although the radiolysis of potassium and sodium chlorates has been investigated,there has been only one paper published on the transfer annealing of in caesium pwchlorate during the period of this Report.
