Product Description

99.5% carbonate potassium cas 584-08-7 potassium carbonate
Potassium carbonate (K₂CO₃) is a white salt, soluble in water (insoluble in ethanol) which forms a strongly alkaline
solution.

It can be made as the product of potassium hydr oxide's absorbent reaction with carbon dioxide.
It is deliquescent, often appearing a damp or wet solid.
Potassium carbonate is used in the production of soap and glass.  

 

History

Potassium carbonate is the primary component of potash and the more refined pearl ash or salts of tartar. Historically, pearl ash was created by baking potash in a kiln to remove impurities. The fine, white powder
remaining was the pearl ash. The first patent issued by the US Patent Office was awarded to Samuel Hopkins in 1790 for an improved method of making potash and pearl ash.
In late 18th century North America, before the development of baking powder, pearl ash was used as a leavening agent in quick breads.
