Easy ionization has led to its application in ion engines, though it was found to be less effective than cesium [1]. Sometimes, rubidium nitrate is used in fireworks to produce a purple color [1]. Another compound, rubidium carbonate, is used to make optical glasses [24]. High accuracy ...
In January 1839, lanthanum was extracted by Carl Mosander while working on his sample of cerium at the Karolinska Institute in Sweden[1]. He took powdered cerium nitrate and treated it with dilute nitric acid[5]. He observed that some of the nitrate powder dissolved in the acid, and then...
Because cesium and rubidium are very similar chemically, their separation presented numerous problems before the advent of ion-exchange methods and ion-specific complexing agents such as crownethers. Once pure salts have been prepared, it is a straightforward task to convert them to the free metal....
(Na2CO3), andsodium nitrate(NaNO3). Oxygen is present as the oxideion, O2-, in the crystalline structure of solid metallic oxides such ascalcium oxide, CaO. Metallic superoxides, such as potassium superoxide, KO2, contain the O2-ion, whereas metallic peroxides, such as barium peroxide, BaO2...
