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. It is isostructural with potassium salt. [3]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise.
The phosphate, [34] acetate, carbonate, halides, oxide, nitrate, and sulfate salts are water-soluble. ... Caesium vapour is used in many common magnetometers.
Notable examples include alkali metals, lithium through caesium, and alkaline earth metals, magnesium through barium. Some water-reactive substances are also pyrophoric, like organometallics and sulfuric acid. The use of acid-resistant gloves and face shield is recommended for safe handling; fume hoods are another effective control of such ...
Cerium is the second element in the lanthanide series, and while it often shows the oxidation state of +3 characteristic of the series, it also has a stable +4 state that does not oxidize water. It is considered one of the rare-earth elements .
Accused murderer Luigi Mangione’s grandmother reportedly left tens of millions of dollars to her children and grandchildren after she died, but did so on one condition: that any grandchild ...
Rubidium, being denser than potassium, sinks in water, reacting violently; caesium explodes on contact with water. [18] However, the reaction rates of all alkali metals depend upon surface area of metal in contact with water, with small metal droplets giving explosive rates. [19] Rubidium has also been reported to ignite spontaneously in air. [11]
