disodium oxalate การใช้

• Disodium oxalate can act as a reducing agent, and it may be used as a primary standard for standardizing potassium permanganate ( KMnO 4 ) solutions.
• To calculate the acid dissociation constant ( pK a ), one must find the volume at the half-equivalence point, that is where half the amount of titrant has been added to form the next compound ( here, sodium hydrogen oxalate, then disodium oxalate ).
