Caesium sulfate or cesium sulfate is the inorganic compound and salt with the formula Cs 2 SO 4. It is a white water-soluble solid that is used to prepare dense aqueous solutions for use in isopycnic (or "density-gradient") centrifugation .
Caesium (IUPAC spelling; [9] also spelled cesium in American English) is a chemical element; it has symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F; 301.6 K), which makes it one of only five elemental metals that are liquid at or near room temperature .
Caesium bisulfate or cesium hydrogen sulfate is an inorganic compound with the formula CsHSO 4. The caesium salt of bisulfate, it is a colorless solid obtained by combining Cs 2 SO 4 and H 2 SO 4 .
Cerium(IV) sulfate, also called ceric sulfate, is an inorganic compound. It exists as the anhydrous salt Ce(SO 4) 2 as well as a few hydrated forms: Ce(SO 4) 2 (H 2 O) x, with x equal to 4, 8, or 12. These salts are yellow to yellow/orange solids that are moderately soluble in water and dilute acids.
The complex [Ce(NO 3) 6] 2− is 12-coordinate, a high coordination number which emphasizes the large size of the Ce 4+ ion. CAN is a popular oxidant in organic synthesis , both as a stoichiometric reagent [ 26 ] and as a catalyst. [ 27 ]
In mass spectrometry, the molecular mass of a small molecule is usually reported as the monoisotopic mass: that is, the mass of the molecule containing only the most common isotope of each element. This also differs subtly from the molecular mass in that the choice of isotopes is defined and thus is a single specific molecular mass out of the ...
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.
