 Potassium carbonate - Wikipedia, the free encyclopedia
Potassium carbonate is a white salt, soluble in water (insoluble in alcohol), which forms a strongly alkaline solution.
Potassium carbonate was first identified in 1742 by Antonio Campanella and is the primary component of potash and the more refined pearlash or salts of tartar.
The resulting potassium hydroxide is then carbonated using carbon dioxide to form potassium carbonate, which is often used to produce other potassium compounds.
