In this project, I can confirmed that based on my readings, green plants and vegetables have higher amount of vitamin C compared to oranges as we always heard. Vitamin C also soluble in water, which, if we consume more than 40mg-70mg per day, it will be removed in our urine. Therefore, there is no need of us taking supplement or any type of vitamin C, as our body will used as much as we need. In this project, I learned that cooking or keeping food in refrigerator for a long time will reduce the amount of vitamin C in that food itself. Therefore, another method of cooking can be apply to maximize the intake of vitamin C in our body.

After done the experiment, I am able to know how to measure
vitamin C in food sample. Vitamin C will denatured in a high temperature when
be heated. So, if we heat a food that contain vitamin C with a strong heat, the
vitamin C in the food will lost. Some recommended way to prepare food with
vitamin C contained is by steaming it. I also know that food containing most
highest vitamin C is citrus. I am also
know why the reason solution of food sample change colour to blue-black.
Vitamin C will react with iodine until no more vitamin C present in the food
and it will change the colour to blue-black. This is called the end point of
the titration. I hope with this new information, I can improve my knowledge and
skill while conducting experiment.

Overall, the lab was an
extremely interesting activity as it showcased the delicate procedures in
conducting such delicate measurements. It was a great learning experience in
trying out a rendition of a titration at its steps. With
the help of group mates, it did showed the systematic and patience that is needed
in such a lab activity. Moreover, the lab
connected fundamental ideas that involved reactions of different solutions and
how to model them through different trials to predict certain concentrations of
solutions. To end off, it was a very spectacular lab.
