Vitamin C concentration (Bio lab report) essays What is the concentration level of vitamin C in freshly squeezed orange juice, Fanta, Nikoline and Rigtig Juice. How does the soda compare to real juices? Will the freshly squeezed orange juice contain more vitamin C than the sodas?

Independent Type of Juice Amount of juice added Dependent Concentration of Vitamin C 20 test tubes (4 solutions * 5 trials) Step one: To properly collect the data it would be best to make a table with the solution of the left side and the number of trials on the top. Be sure that each trial has enough space to note down the drops of Iodine needed to show the concentration (Ill explain this in further detail later) and the vitamin C concentration of mg/L. We chose to have 5 different trials and average them all to ensure a better accuracy. Step two: Put 1 ml of each substance into 4 test tubes. Remember to mark each tube so you know what is what. Now that you have the solutions, youre now ready to start the experiment. F ...
