Rubidium is the 18th most abundant element in seawater. [15]: 371 Because of its large ionic radius, rubidium is one of the "incompatible elements". [34] During magma crystallization, rubidium is concentrated together with its heavier analogue caesium in the liquid phase and crystallizes last.
Another method is to neutralize rubidium carbonate with hydriodic acid: [1] Rb 2 CO 3 + 2HI → 2RbI + H 2 O + CO 2. Another method is to use rubidium metal to react directly with iodine, but because rubidium metal is very expensive, it is the least commonly used method. In addition, rubidium reacts violently with halogens and burns: [1] 2Rb ...

Rubidium chloride is the chemical compound with the formula RbCl. This alkali metal halide salt is composed of rubidium and chlorine , and finds diverse uses ranging from electrochemistry to molecular biology .
The rubidium content in minerals is often calculated and quoted in terms of Rb 2 O. In reality, the rubidium is typically present as a component of (actually, an impurity in) silicate or aluminosilicate. A major source of rubidium is lepidolite, KLi 2 Al(Al,Si) 3 O 10 (F,OH) 2, wherein Rb sometimes replaces K. Rb 2 O is a yellow colored solid.
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 bromide is an inorganic compound with the chemical formula Rb Br. It is a salt of hydrogen bromide. It consists of bromide anions Br − and rubidium cations Rb +. It has a NaCl crystal structure, with a lattice constant of 685 picometres. [1] There are several methods for synthesising rubidium bromide.
In addition to simple rubidium fluoride, an acidic rubidium fluoride with the molecular formula HRbF 2 is also known, [4] which can be produced by reacting rubidium fluoride and hydrogen fluoride. [4] The compounds H 2 RbF 3 and H 3 RbF 4 were also synthesized. [5] [4] The solubility in acetone is 0.0036 g/kg at 18 °C and 0.0039 g/kg at 37 °C ...
