Description
Potassium carbonate (molecular formula: K2CO3), also known as potash or pearl ash, appears as a white powder or as colorless solid crystal with salty taste and deliquescence. It can be dissolved in water to form a strongly alkaline solution. However, it is insoluble in organic solvents such as ethanol. It has wide applications. For example, it can be used as a drying agent, buffering agent and a source of potassium in laboratory. It can also be used for the manufacturing of fire extinguishers, soap, glass, and soften water. In addition, it is also used during the production of cocoa powder to balance pH. Moreover, it can be supplied to effervescent tablets which can conveniently provide potassium when there are low levels of potassium in the blood for patients caused by various kinds of factors. In industry, potassium carbonate is manufactured though first performing electrolysis of potassium chloride to generate potassium hydroxide, followed by reaction with carbon dioxide to derive the product. It is toxic upon eye contact, inhalation and ingestion. For rats, it has an oral LD50 being 1870 mg/kg. It has chronic effects on humans, causing damage to the mucous membranes, skin, and eyes.More related product prices
