    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's been a while since you posted and nobody's replied yet...maybe you should check out MarkedbyTeachers.com, TSR's sister site. It has the largest library of essays in the UK.

    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.
