How do you test an apple for vitamin C?
1. Crush the apple and shake it in warm water to extract the soluble substances 2. Take some of the water that had the apple in it and add it to 2cm3 of a 0.1% solution of DCIP (a blue dye) 3. If vitamin C is present, the blue dye will go colourless
What is a DCPIP indicator for?
