Rubidium Oxalate
Rubidium oxalate is a chemical compound with the chemical formula . It is a rubidium salt of oxalic acid. It consists of rubidium cations and oxalate anions . Rubidium oxalate forms a monohydrate . Preparation Rubidium carbonate and oxalic acid react to form rubidium oxalate: : Rubidium oxalate can also be obtained via the thermal decomposition of rubidium formate: : Properties From an aqueous solution, rubidium oxalate crystallizes as a monohydrate in the monoclinic crystal system. and is isomorphic to potassium oxalate monohydrate . Two forms of the anhydrous form () exist at room temperature: one form is monoclinic and isotypic to caesium oxalate (), the other is orthorhombic and isotypic to potassium oxalate (). Freshly prepared anhydrous rubidium oxalate initially contains mainly the monoclinic form, but this slowly transforms irreversibly into the orthorhombic form. In 2004, two more high-temperature forms of rubidium oxalate were discovered. Crystal data of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubidium Carbonate
Rubidium carbonate, Rubidium, Rb2Carbon, COxygen, O3, is a convenient compound of rubidium; it is stable, not particularly reactive, and readily soluble in water, and is the form in which rubidium is usually sold. Preparation This salt can be prepared by adding ammonium carbonate to rubidium hydroxide. Uses It is used in some kinds of glass-making to enhance stability and durability and reduce conductivity. It is also used as a part of a catalyst to prepare short-chain alcohols from feed gas. References [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
