Ammonium Oxalate Extra Pure
Original price was: $ 19.00.$ 18.96Current price is: $ 18.96.
Ammonium Oxalate Extra Pure is a high-purity, white crystalline compound commonly used in laboratory chemistry for analytical and inorganic applications. It is particularly valuable in the qualitative and quantitative analysis of calcium, where it forms an insoluble calcium oxalate precipitate. This makes it essential in hardness testing of water and other gravimetric determinations. It also finds use in buffer solutions and as a complexing agent in metal ion analysis. The extra pure grade ensures low levels of interfering substances, making it ideal for sensitive analytical work. Ammonium oxalate should be stored in a tightly sealed container in a cool, dry place to maintain stability and prevent degradation.
