Potassium carbonate

Description:

Potassium carbonate (K2CO3) is an inorganic salt characterized by its white, crystalline appearance and hygroscopic nature, meaning it can absorb moisture from the air. It is highly soluble in water, forming an alkaline solution, which makes it useful in various applications, including as a buffering agent and in glass manufacturing. The compound has a relatively high melting point and decomposes upon heating, releasing carbon dioxide and potassium oxide. Potassium carbonate is commonly used in agriculture as a fertilizer, providing potassium essential for plant growth. Additionally, it serves as a key ingredient in the production of soaps and detergents, as well as in the food industry as a food additive (E501). Its ability to act as a drying agent and its role in chemical synthesis further highlight its versatility. While generally considered safe for use in food and agriculture, it should be handled with care, as it can cause irritation to the skin and eyes upon contact.

Potassium carbonate

Controlled Product

CAS: 584-08-7

Potassium carbonate is a white crystalline salt that is soluble in water. It has the chemical formula K2CO3 and its molecular weight is 98.0 g/mol. Potassium carbonate has been used as a buffering agent, in the manufacture of glass, soap, and fertilizer. It also has been used to treat infectious diseases such as malaria and tuberculosis. Potassium carbonate can be used to stop the growth of bacteria by inhibiting their DNA replication due to its ability to bind potassium ions. This results in the inhibition of polymerase chain reaction (PCR) and DNA synthesis by complex enzymes such as DNA gyrase and topoisomerase IV. The phase transition temperature for potassium carbonate is around 40°C, which means it will decompose at this temperature or above. When exposed to CO2 flow, potassium carbonate will react with CO2 to form water vapor (H2O) and anhydrous sodium carbonate (Na2CO3).
