Ethanedioic acid, potassium salt, hydrate (2:1:2)

Description:

Ethanedioic acid, potassium salt, hydrate (2:1:2), commonly known as potassium oxalate, is an inorganic compound with the formula K2C2O4·2H2O. This substance typically appears as a white crystalline solid and is highly soluble in water, making it useful in various applications, including as a reagent in analytical chemistry and as a food additive. The compound is characterized by its ability to form complexes with metal ions, which is significant in both biological and industrial processes. It has a slightly acidic nature due to the presence of oxalate ions, which can form insoluble precipitates with certain metal ions, such as calcium. In terms of safety, potassium oxalate is considered toxic if ingested in large quantities, as it can lead to oxalate poisoning, affecting kidney function. Proper handling and storage are essential to mitigate risks associated with exposure. Overall, potassium oxalate serves important roles in both laboratory settings and various industrial applications.
