In this experiment, you will be running multiple trials, each with a TOTAL volume of 35 mL, but with an increasing the amount of vinegar in that mixture each time. What you think will happen as you go from trial 1 all the way through trial 8? The highest amount of NaHCO3 will react in trial #1. The highest amount of NaHCO3 will react in trial #8. The amount of NaHCO3 will react more and more with each trial until a certain point, at which it doesn't matter how much vinegar is added because all of the NaHCO3 will be used up. The amount of NaHCO3 will react less and less with each trial until a certain point, at which it doesn't matter how much vinegar is added because all of the vinegar will be used up.
