The amount of 0.05 vitamin C solution needed to reduce the DCPIP is recorded.Conclusion. This experiment has shown the vitamin C content of a small variety of juices, but different brands contain different amounts of vitamin C so it has not proved a great deal. Aims and Objectives This experiment is conducted in order to investigate which fruit, kiwi fruit, lemon fruit or orange fruit contain more vitamin C - Dcpip Testr introduction. Search Results of How test for vitamin c using dcpip.Measuring vitamin C in food - a global experiment. Royal Society of Chemistry 4 years ago. As with all experiment, repeat your readings to check for anomalies and remember you should1. If you know the concentration of the DCPIP (the school technicians should be able to tell you), you can work backwards using the titration calculation to find out the concentration of vitamin C in the juice. Take juice in 1ml pipette and titrate it against 2ml DCPIP solution.28 Conclusion From our experiment we thus conclude that homemade juice has the most vitamin c concentration when compared to available market juices. What this experiment sought to find out was exactly what kind of drink was better in terms of dietary vitamin C. The juices were titrated into a set amount of DCPIP and measuring how many millilitres it took for the DCPIP to turn from blue to clear.
