Ok, thank you all very much.
Needless to say, I feel a bit over my head right now, but I think I am beginning to understand what you are saying.
One thing I do understand is that in order to determine the right equation for my experiment, I have to use the Acid + Base -> Salt + Water equation. What my teacher said, is that I have to determine how many H's will be given off from the Citric Acid in order to form water. Now, I havn't determined this yet, though I think I am getting close.
Again, thank you all very much. I will post again if I have any further questions, which undoubtably I will.
