Caesium carbonate is a white crystalline solid of formula Cs 2 CO 3. 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:
