Potassium Carbonate


Potassium Bicarbonate

Potassium Carbonate, Potassium Bicarbonate and Magnesium Carbonate can be used as pH regulator, nutrient, food additive, pharmaceutical ingridient, yeast, baking powder, Swelling Agent, additive for beverage, infant formula powder etc.

Sodium carbonate ("soda" or "natron") and potassium carbonate ("potash") have been used since antiquity for cleaning and preservation, as well as for the manufacture of glass. Carbonates are widely used in industry, e.g. in iron smelting, as a raw material for Portland cement and lime manufacture, in the composition of ceramic glazes, in Food Additive and beverage ingredients, in pharmaceutical raw materials etc..

In aqueous solution, carbonate, bicarbonate, carbon dioxide, and carbonic acid exist together in a dynamic equilibrium. In strongly basic conditions, the carbonate ion predominates, while in weakly basic conditions, the bicarbonate ion is prevalent. In more acid conditions, aqueous carbon dioxide, CO2(aq), is the main form, which, with water, H2O, is in equilibrium with carbonic acid – the equilibrium lies strongly towards carbon dioxide. Thus sodium carbonate is basic, sodium bicarbonate is weakly basic, while carbon dioxide itself is a weak acid.
Carbonated water is formed by dissolving CO2 in water under pressure. When the partial pressure of CO2 is reduced, for example when a can of soda is opened, the equilibrium for each of the forms of carbonate (carbonate, bicarbonate, carbon dioxide, and carbonic acid) shifts until the concentration of CO2 in the solution is equal to the solubility of CO2 at that temperature and pressure. In living systems an enzyme, carbonic anhydrase, speeds the interconversion of CO2 and carbonic acid.
Although the carbonate salts of most metals are insoluble in water, the same is not true of the bicarbonate salts. In solution this equilibrium between carbonate, bicarbonate, carbon dioxide and carbonic acid changes consonant to changing temperature and pressure conditions. In the case of metal ions with insoluble carbonates, e.g. CaCO3, formation of insoluble compounds results. This is an explanation for the buildup of scale inside pipes caused by hard water.

Potassium carbonate (K2CO3) is a white salt, which is soluble in water (insoluble in ethanol)[2] and forms a strongly alkaline solution. It can be made as the product of Potassium Hydroxide'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.

potassium carbonate is prepared commercially by the electrolysis of Potassium Chloride. The resulting potassium Hydroxide is then carbonated using carbon dioxide to form potassium carbonate, which is often used to produce other Potassium compounds.

Potassium carbonate was historically for soap, glass, and china production.
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 noodles and moon cake. It is used to tenderize tripe. German gingerbread recipes often use potassium carbonate as a baking agent.
in the production of cocoa powder to balance the pH (i.e., reduce the acidity) of natural cocoa beans; it also enhances aroma.
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.
