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 naturally. The rubidium content in minerals is often calculated and quoted in terms of
Rubidium hydroxide is the inorganic compound with the formula RbOH. It consists of rubidium cations and an equal number of hydroxide anions. It is a colorless solid that is commercially available as aqueous solutions from a few suppliers. Like other strong bases, rubidium hydroxide is highly caustic. Rubidium hydroxide is formed when rubidium ...
Rubidium is the first alkali metal in the group to have a density higher than water. On Earth, natural rubidium comprises two isotopes: 72% is a stable isotope 85 Rb, and 28% is slightly radioactive 87 Rb, with a half-life of 48.8 billion years – more than three times as long as the estimated age of the universe.
Rubidium chloride is an excellent non-invasive biomarker. The compound dissolves well in water and can readily be taken up by organisms. Once broken in the body, Rb + replaces K + in tissues because they are from the same chemical group. [9] An example of this is the use of a radioactive isotope to evaluate perfusion of heart muscle.
Rubidium hydride is the hydride of rubidium. With the formula RbH, it is classified as an alkali metal hydride. It is a white solid and is insoluble in most solvents. It is synthesized by treating rubidium metal with hydrogen. Rubidium hydride is a powerful superbase and reacts violently with water.
Rubidium carbonate, Rb 2 C O 3, 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
Rubidium iodide forms colorless crystals, and has a red-violet flame color. The refractive index of the crystals is n D = 1.6474. [2] It reacts with halogens to form polyhalides: RbI 3, RbICl 2, RbICl 4. [3] It is easily soluble in water, liquid ammonia, sulfuric acid, RbI·6NH 3 and RbI·3SO 2. Rubidium iodide is soluble only in the following ...
Rubidium sulfate is a sulfate of rubidium. The molecular formula of the compound is Rb 2 SO 4. The molecular weight of this compound is 266.999 g/mol. [1] An acid sulfate of rubidium (rubidium hydrogen sulfate) can be formed. It is soluble in water and is an aqueous solution. [1]
