|
Potassium carbonate (K2CO3) is a white salt (sometimes colorless), soluble in pure water (insoluble in alcohol), which forms a strongly alkaline solution. It can be manufactured as the product of potassium hydroxide's absorbent reaction with carbon dioxide. It is deliquescent, often appearing a colorless damp or wet solid. Potassium carbonate is used in the production of bath soap and glass.
History
Antonio Campanella identified Potassium carbonate in around 1742 and it is the main 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 and dirt. The fine white colorless powder remaining was the pearl ash. The first patent was issued by the U.S. Patent Office and was awarded to Samuel Hopkins in 1790 for an improved and better method of making potash and pearl ash.
[1]
In early 19th century in North America, before the development and produce of baking powder, pearl ash was used as a leavening agent in quick breads.
