Caesium carbonate 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 to give carbon dioxide gas, water, and a caesium salt as follows:
- Cs2CO3 + 2HCl -> 2CsCl + H2O + CO2
