The Most Enzyme Concentration Of Orange Juices Experiment Results

OBJECTIVE: The purpose of this experiment was to see which type of orange juice will have the most vitamin C to the point where it will change colors.
HYPOTHESIS: Orange juices labeled A will have the most enzyme concentration because it looked thicker than the others. Therefore I thought it will need more Iodine whilst orange juice labeled B & C will need less Iodine because they looked lighter.
Variables
Independent: the amount of Iodine that was added to the the different types of orange juice
Dependent: The color of the orange juice changed to dark purple depending on how much iodine that was put into orange juices.
Controlled: the temperature of the orange juices and the amount of orange juices.
Materials/Procedures: In this lab, Dr. Bennett supplied us with 3 different brands of orange juices labeled A, B, C.Next, he gave us cornstarch, stirring rods,2 beakers one that measured 100 ml and the other that measured 50 ml for when we run out the
Bennett supplied us with 3 different brands of orange juices labeled A, B, C.Next, he gave us cornstarch, stirring rods,2 beakers one that measured 100 ml and the other that measured 50 ml for when we run out the test.Then, he gave us 25ml graduated cylinder and finally an electric balance.So we proceeded to get approximately 50 ml of juices sample A for the directed location and put it into the 100ml beaker.Then we measured 20 ml and put into the 50ml beaker.Next, we used the electric balance making sure that we put our measuring boat on it and zero it out before we add our 0.5 grams of cornstarch to the juice.Next, we used the stirring rods to stir it carefully.Then, as we stirred we gradually added Iodine it was no longer orange but dark purple.We then record how many drops it took to change the orange juices color.Next, we repeat steps 1-5 ten add the two numbers and divide my two.Finally, we repeat procedure 1-7 for the oranges juices B, C, and vitamin c
