Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
Caesium hydride or cesium hydride is an inorganic compound of caesium and hydrogen with the chemical formula Cs H. It is an alkali metal hydride . It was the first substance to be created by light-induced particle formation in metal vapor, [ 2 ] and showed promise in early studies of an ion propulsion system using caesium. [ 3 ]
A water molecule in the first solvation shell of an aqua ion may exchange places with a water molecule in the bulk solvent. It is usually assumed that the rate-determining step is a dissociation reaction. [M(H 2 O) n] z+ → [M(H 2 O) n-1] z+ * + H 2 O. The * symbol signifies that this is the transition state in a chemical reaction. The rate of ...
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 .

Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Similar to sodium sulfide, anhydrous cesium sulfide can be produced by reacting cesium and sulfur in THF.It needs ammonia or naphthalene to react. [4]2 Cs + S → Cs 2 S. By dissolving hydrogen sulfide into cesium hydroxide solution, it will produce cesium bisulfide, then it will produce cesium sulfide too.
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 .
