NettetProcedures. An amount of 0.5g of DCPIP (dichlorophenolindophenol) powder was measured on an electronic scale. Next, 500ml of distilled water were then mixed together to form 500ml of 0.1% DCPIP solution, which was stored in a dark bottle. The solution was a dark blue colour. DCPIP is used for the testing of vitamin C. Nettet2,6 -dichlorophenol -indophenol or DCPIP. You need to standardise this against a known concentration of vitamin C. This means finding out how much DCPIP reacts with a known amount of vitamin C. You can check the end point colour by testing a small amount of vitamin C with the DCPIP and observe the disappeara nce of the blue colour.
