| Introduction | rubidium chloride is an alkali metal halide, chemical formula RbCl, white crystalline powder, soluble in water, slightly soluble in alcohol. In the gaseous state, RbCl is a diatomic molecule with a bond length of about 2.7868. In the cubic system, the bond length is increased by 3.285, which shows a high ion coordination number in the solid state. |
| preparation | rubidium chloride is mainly recovered from lithium Lepidolite and brine tailings, it is also extracted from relatively enriched rubidium-containing carnallite and rubidium-rich mineral water. The most common method for preparing pure rubidium chloride is to mix rubidium hydroxide and hydrochloric acid and then purify by recrystallization: RbOH(aq) HCl(aq) → RbCl(aq) H2O(l) another approach takes advantage of the equilibrium of Na, NaCl, Rb and RbCl at high temperature: Rb(s) NaCl(s) RbCl(l) Na(s) another expensive method is to react with rubidium metal and halogen: 2Rb(s) Cl2 (g) → 2RbCl(s) RbCl is hygroscopic and must therefore react with atmospheric moisture by Isolation, for example using a desiccant. RbCl is mainly used in the laboratory. Thus, many chemical agents can supply varying amounts of rubidium chloride to meet a variety of chemical and biochemical research needs. |
| Application | Analysis of sodium, Iridium, titanium, zirconium and perchlorate; raw materials for the preparation of metal rubidium by calcium reduction and raw materials for the preparation of other rubidium salts and isotope separations. It is mainly used for electrolytic preparation of metal rubidium, and also used for aluminum brazing agent. |
| solubility in water (g/100ml) | grams dissolved per 100ml of water at different temperatures (℃): 77g/0 ℃;84g/10 ℃;91g/20 ℃;98g/30 ℃;104g/40 ℃ 115g/60 ℃;127g/80 ℃;133g/90 ℃;143g/100 ℃ |
| Use | Analysis of sodium, Iridium, titanium, zirconium and perchlorate; raw materials for preparation of metal rubidium by reduction of calcium and raw materials for preparation of other rubidium salts and isotope separation |
