IB Biology Lab – Vitamin C content of food Aim: To compare the vitamin C content of different fruits using the decolourisation of DCPIP from blue to clear as the indicator. • You first need to estimate the volume of a known concentration of vitamin C solution required to decolourise 2 cm3 of DCPIP solution. • Then you need to determine the volume of fruit juice that decolourises 2 cm3 of DCPIP solution. This gives an estimate of the concentration of vitamin C in fruit juice. • This
