Potassium oxalate

Description:
Potassium oxalate, with the CAS number 10043-22-8, is an inorganic compound that appears as a white, crystalline solid. It is the potassium salt of oxalic acid and is commonly encountered in its dihydrate form, which contains two molecules of water. This compound is highly soluble in water, making it useful in various applications, including as a reagent in analytical chemistry and as a buffering agent. Potassium oxalate is known for its ability to form complexes with metal ions, which can be significant in processes such as metal extraction and purification. It is also utilized in the textile and dye industries. However, it is important to note that potassium oxalate can be toxic if ingested in large quantities, as oxalates can interfere with calcium absorption and lead to the formation of kidney stones. Proper handling and safety precautions are essential when working with this substance in laboratory or industrial settings.
