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 .
Rubidium is a very soft, ductile, silvery-white metal. [11] It has a melting point of 39.3 °C (102.7 °F) and a boiling point of 688 °C (1,270 °F). [12] It forms amalgams with mercury and alloys with gold, iron, caesium, sodium, and potassium, but not lithium (despite rubidium and lithium being in the same periodic group). [13]
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
The temperature at standard pressure should be equal to the normal boiling point, but due to the considerable spread does not necessarily have to match values reported elsewhere. log refers to log base 10 (T/K) refers to temperature in Kelvin (K) (P/Pa) refers to pressure in Pascal (Pa)
This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia. ... 37 Rb rubidium; use: 961 K: 688 ...
Ruthenium is the first in a downward trend in the melting and boiling points and atomization enthalpy in the 4d transition metals after the maximum seen at molybdenum, because the 4d subshell is more than half full and the electrons are contributing less to metallic bonding.
It is a white solid with a melting point of 642 °C. Preparation ... Rubidium iodide has a sodium chloride structure; its lattice constant is a = 7.326 Å, ...
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 ...
