silverst23 Posted January 11, 2019 Report Share Posted January 11, 2019 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!!!

kw0573 Posted January 11, 2019 Report Share Posted January 11, 2019 If the container is sealed, temperature should not change concentration of citric acid. I think you need to review your acid and bases. An increase in acid concentration will decrease pH. Pick a topic you know more about. Reply Link to post Share on other sites More sharing options...
Ntwali Posted January 12, 2019 Report Share Posted January 12, 2019 Or if you still want to chose between the two topics you should totally research about both of them then try to see which one is better. I am also kinda having a problem choosing a topic. The worst part is that I don't even have alternatives Reply Link to post Share on other sites More sharing options...
