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.
caesium selenate can be obtained from the reaction of caesium carbonate and selenic acid solution: [2] Cs 2 CO 3 + H 2 SeO 4 → Cs 2 SeO 4 + H 2 O + CO 2 ↑. caesium selenate can also be prepared by the neutralization reaction of selenic acid and caesium hydroxide: [1] 2 CsOH + H 2 SeO 4 → Cs 2 SeO 4 + 2 H 2 O
Caesium carbonate can also be used as the base: Cs 2 CO 3 + HN 3 → CsN 3 + CO 2 + H 2 O. Caesium sulfate reacts with barium azide to form insoluble barium sulfate and caesium azide: Cs 2 SO 4 + Ba(N 3) 2 → 2CsN 3 + BaSO 4 ↓. The thermal decomposition of CsN 3 in vacuo can be used as a method of generating high purity caesium metal: [5] 2 ...
