Caesium carbonate (or cesium carbonate in the US) is a white crystalline solid of formula Cs2CO3. It is more soluble in organic solvents than many other carbonates such as potassium carbonate, and therefore finds use as a base in organic chemistry.
Characteristic of carbonate salts, it reacts with protic acids such as hydrochloric acid to give carbon dioxide gas, water, and a caesium salt as follows:
This may be used as a way to produce other caesium salts.
