Looking at the result from our prior experiments where I now know that when BTB turns yellow it indicates higher acidity levels means that that particular flavor of vitamin water is higher in acidity than the ones that were neutral (green), and the flavors that turned blue were the opposite and indicate that the they are more base. The purpose is to observe the macroscopic changes that these chemicals undergo. Phenolphthalein clear liquid Color was almost Identical to BTB, dark blue. How might you interpret this result?
