    So i figured out the concentratino for different solutions. However, i think i made a mistake - freshly squashed orange juice took three drops for the colour to change and the concentration is less compared to the others. Shouldn't the concentration should be more because there is a lot more of vitamin C in it?:confused:

    It should but orange is less acidic than other citrus fruits.

    If it's more concentrated, you would need fewer drops for it to change the colour of the DCPIP.
