1. For a system with a starting pH of 8.0: a. What would be dominant carbonate species and why? (5 points) b. If you added acid to the system (i.e., titration), how would that affect the carbonate species in your system and why? (5 points) c. If you have two systems with a starting pH of 8.0 but one with much greater carbonate than the other, how would this affect the amount of titrant if the acidity is constant? Think of this titration as having two separate volumes of water with different amounts of carbonate and titrating with the same acid. (10 points)
