Key Properties
Potassium tetraoxalate dihydrate, with a CAS number of 6100-20-5, is an acidic potassium oxalate salt that serves as a primary standard for the standardization of base solutions. This compound is notable for its high purity of 99.5%, making it suitable for analytical applications in laboratories. It is a dihydrate, meaning it contains two molecules of water for each molecule of potassium tetraoxalate, which is important for its stability and handling. The compound is widely used in titrations and other quantitative chemical analyses, particularly in the determination of the concentration of alkaline solutions.
Also known as Potassium oxalate, dihydrate.
