General description

Potassium carbonate (K2CO3) is a water-soluble inorganic compound that is primarily derived from potash. It is industrially prepared by reacting potassium hydroxide and carbon dioxide. The solution crystallizes to form potash hydrate, which can further be heated above 200°C to produce the anhydrous salt.
