How should I standardise dcpip for an experiment to find the vitamin C content of orange juices?
Ulex says ...
You need to make up a standard solution of vit.C by dissolving a known mass of the dry solid in water and making the volume up to the mark in a standard (volumetric ) flask.
Titrate pipette volumes of this with the dye solution and work out the average of several titrations. You then know how much dye solution is equivalent to what quantity of Vit C.
