Potassium carbonate is the inorganic compound with the formula K2CO3. It is a white salt, which is soluble in water. It is deliquescent, often appearing as a damp or wet solid. Potassium carbonate is mainly used in the production of soap and glass.Other names also include Carbonate of potash, Pearl ash, Salt of tartar.

Applications

  • (historically) for soap, glass, and china production
  • as a mild drying agent where other drying agents, such as calcium chloride and magnesium sulfate, may be incompatible. It is not suitable for acidic compounds, but can be useful for drying an organic phase if one has a small amount of acidic impurity. It may also be used to dry some ketones, alcohols, and amines prior to distillation.
  • in cuisine, where it has many traditional uses. It is an ingredient in the production of grass jelly, a food consumed in Chinese and Southeast Asian cuisines, as well as Chinese hand-pulled noodles, and moon cake. It is used to tenderize tripe. German gingerbread recipes often use potassium carbonate as a baking agent, although in combination with hartshorn. It is however important that the right quantities are used to prevent harm, and cooks should not use it without guidance.
  • in the alkalization of cocoa powder to produce Dutch process chocolate by balancing the pH (i.e., reduce the acidity) of natural cocoa beans; it also enhances aroma. The process of adding potassium carbonate to cocoa powder is usually called "Dutching" (and the products referred to as Dutch-processed cocoa powder), as the process was first developed in 1828 by Coenrad Johannes van Houten, a Dutchman.
  • as a buffering agent in the production of mead or wine.
  • in antique documents, it is reported to have been used to soften hard water.
  • as a fire suppressant in extinguishing deep-fat fryers and various other B class-related fires.
  • in condensed aerosol fire suppression, although as the byproduct of potassium nitrate.
  • as an ingredient in welding fluxes, and in the flux coating on arc-welding rods.
  • as an animal feed ingredient to satisfy the potassium requirements of farmed animals such as broiler breeders.
  • as an acidity regulator in Swedish snus
