Description

Potassium carbonate is a white, water-soluble salt with the chemical formula K2CO3. It forms strong alkaline solutions and is a basic salt. It is typically produced by the chemical reaction between potassium hydroxide or caustic potash (KOH) and carbon dioxide (CO2). A hygroscopic substance, it often appears as a water-based solid. It is commonly used in the manufacture of soap and glass, is the main component of natural caustic potash, and is also used as an additive in planted aquariums.
