Molar mass: 120.921 g/mol Appearance white crystals hygroscopic: Density: 2.80 g/cm 3 (25 °C) ... Rubidium chloride is the chemical compound with the formula RbCl.
The two scientists used the rubidium chloride to estimate that the atomic weight of the new element was 85.36 (the currently accepted value is 85.47). [39] They tried to generate elemental rubidium by electrolysis of molten rubidium chloride, but instead of a metal, they obtained a blue homogeneous substance, which "neither under the naked eye ...
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
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 ...
Tris(bipyridine)ruthenium(II) chloride is the chloride salt coordination complex with the formula [Ru(bpy) 3]Cl 2.This polypyridine complex is a red crystalline salt obtained as the hexahydrate, although all of the properties of interest are in the cation [Ru(bpy) 3] 2+, which has received much attention because of its distinctive optical properties.
