Rubidium oxide is the chemical compound with the formula Rb 2 O. Rubidium oxide is highly reactive towards water, and therefore it would not be expected to occur ...
Rubidium ozonide is an oxygen rich compound of rubidium. It is an ozonide , meaning it contains the ozonide anion (O 3 − ). It can be created by reacting rubidium superoxide (RbO 2 ) with ozone (O 3 ) in a liquid ammonia solution.
Rubidium forms a number of oxides when exposed to air, including rubidium monoxide (Rb 2 O), Rb 6 O, and Rb 9 O 2; rubidium in excess oxygen gives the superoxide RbO 2. Rubidium forms salts with halogens, producing rubidium fluoride , rubidium chloride , rubidium bromide , and rubidium iodide .
Rubidium sesquioxide is a chemical compound with the formula Rb 2 O 3 or more accurately Rb 4 O 6.In terms of oxidation states, Rubidium in this compound has a nominal charge of +1, and the oxygen is a mixed peroxide (O 2− 2) and superoxide (O − 2) for a structural formula of (Rb +) 4 (O − 2) 2 (O 2− 2). [4]
It can be created by slowly exposing elemental rubidium to oxygen gas: [3] Rb(s) + O 2 (g) → RbO 2 (s) Like other alkali metal hyperoxides, crystals can also be grown in liquid ammonia. [4] Between 280 and 360 °C, Rubidium superoxide will decompose, leaving not rubidium sesquioxide (Rb 2 O 3), but rather rubidium peroxide (Rb 2 O 2). [3]
Molozonides are unstable and rapidly convert to the trioxolane ring structure with a five-membered C–O–O–C–O ring. [8] [9] They usually appear in the form of foul-smelling oily liquids, and rapidly decompose in the presence of water to carbonyl compounds: aldehydes, ketones, peroxides. Formation of an organic ozonide.
The rest of the Earth's crust is formed also of oxygen compounds, most importantly calcium carbonate (in limestone) and silicates (in feldspars). Water-soluble silicates in the form of Na 4 SiO 4, Na 2 SiO 3, and Na 2 Si 2 O 5 are used as detergents and adhesives. [6] Peroxides retain some of oxygen's original molecular structure ((− O-O −).
In addition to the neutral rubidium oxalate Rb 2 C 2 O 4, there is also an acidic salt, rubidium hydrogen oxalate with the formula RbHC 2 O 4, which is isomorphic to potassium hydrogen oxalate KHC 2 O 4 [10] and forms monoclinic crystals, [11] and an acidic dioxalate with the formula RbHC 2 O 4 ·H 2 C 2 O 4, which exists as a dihydrate, has a ...
