Our teacher told us to make our independent and dependent variables of our research question quantifiable. And so I thought of these as I really want to do titration (Im SL btw) : 1. How does the storage temperature of Sprite affect the concentration of citric acid? ^The problem with this is it even applicable - people usually store their soft drinks either in a fridge or room temperature. So I'm a bit confused and even if it is applicable, I need the intervals of temperature to go up by even intervals. How would I do that? 2. How does concentration of citric acid in Sprite affect the pH? ^The problem here is that it is probably obvious that higher acid concentration gives increased pH. So I should strain away from this right? Do you guys think I could still do one of the following questions. Any help at all is appreciated!!!
