Conclusion:My hypothesis was proven correct. If different fruit drink are combined with iodine the vitamin C within the drinks will be visible due to the color change.Since my control experiment and actual experiment with the fruit drinks had the same outcome it leads me to believe that my results were correct. My observations being that the Orange would contain the most Vitamin C which it did. Although i was surprised when reading on the label that grapefruit juice consists of no vitamin c it was important to test it to defiantly prove it.The hypothesis was supported due to the fact that my control experiment proved the results that would occur. I recognized the independent variable as the different types of fruit drinks I used and the dependent , as the number of drops added to the iodine solution. The controlled variables was the temperature of the fruit drinks , amount of iodine poured into each beaker. Also, the control experiment with the vitamin C tablet and waterin the iodine solution. The chemical change that occurred within this experiment displayed if vitamin C was present
