Caesium carbonate or cesium carbonate is a chemical compound with the chemical formula Cs 2 C O 3. It is white crystalline solid . Caesium carbonate has a high solubility in polar solvents such as water , ethanol and DMF .
Caesium has physical and chemical properties similar to those of rubidium and potassium. It is pyrophoric and reacts with water even at −116 °C (−177 °F). It is the least electronegative stable element, with a value of 0.79 on the Pauling scale. It has only one stable isotope, caesium-133. Caesium is mined mostly from pollucite.
Caesium bicarbonate or cesium bicarbonate is a chemical compound with the chemical formula CsHCO 3. It can be produced through the following reaction: Cs 2 CO 3 + CO 2 + H 2 O → 2 CsHCO 3. The compound can be used for synthesizing caesium salts, but less common than caesium carbonate.
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 .
Sodium salts were added to plain water both as flavoring (to mimic famed mineral waters, such as naturally effervescent Selters, Vichy water and Saratoga Water) and acidity regulators (to offset the acidic 5-6 pH carbonic acid created when carbon dioxide is dissolved in water). [10] In the 1950s the term club soda began to be popularized. [38]
The action of water on rock over long periods of time typically leads to weathering and water erosion, physical processes that convert solid rocks and minerals into soil and sediment, but under some conditions chemical reactions with water occur as well, resulting in metasomatism or mineral hydration, a type of chemical alteration of a rock ...
The salts have extreme non-linear optical properties. [6] K 2 Ce(NO 3) 5 [12] crystals can be grown by evaporating a solution of potassium nitrate, cerous nitrate, and nitric acid. Each cerium atom is surrounded by the oxygen atoms of five bidentate nitrate groups and two water oxygen atoms. [6]
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 ]
