As a liquid, xenon has a density of up to 3.100 g/mL, with the density maximum occurring at the triple point. [53] Liquid xenon has a high polarizability due to its large atomic volume, and thus is an excellent solvent. It can dissolve hydrocarbons, biological molecules, and even water. [54]
Liquid water has a density of approximately 1 g/cm 3 (1 g/mL). Thus 100 mL of water is equal to approximately 100 g. Therefore, a solution with 1 g of solute dissolved in final volume of 100 mL aqueous solution may also be considered 1% m/m (1 g solute in 99 g water).
ρ sol is the density of the solution in g/ml, which is 1.025 g/ml for blood plasma. [ 5 ] c a is the ( anhydrous ) solute concentration in g/ml – not to be confused with the density of dried plasma
Xenon tetroxide is a chemical compound of xenon and oxygen with molecular formula XeO 4, remarkable for being a relatively stable compound of a noble gas.It is a yellow crystalline solid that is stable below −35.9 °C; above that temperature it is very prone to exploding and decomposing into elemental xenon and oxygen (O 2).
These toxic chemicals are avoided today in consideration of the fact that there are alternative water based, non-toxic heavy liquids like sodium polytungstate solutions. [1] With this relatively new heavy liquid densities up to 3.1 g·cm −3 can be adjusted . Adding parts of pulverulent tungsten carbide increases the density to 4.6 g·cm −3. [2]
A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+.The solvation number, n, determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table.
In addition to compounds where xenon forms a chemical bond, xenon can form clathrates—substances where xenon atoms or pairs are trapped by the crystalline lattice of another compound. One example is xenon hydrate (Xe· 5 + 3 ⁄ 4 H 2 O), where xenon atoms occupy vacancies in a lattice of water molecules. [ 32 ]
Iodine-125 is commercially available in dilute NaOH solution as 125 I-iodide (or the hypohalite sodium hypoiodite, NaIO). The radioactive concentration lies at 4 to 11 GBq/mL and the specific radioactivity is > 75 GBq/μmol (7.5 × 10 16 Bq/mol). The chemical and radiochemical purity is high.
