Use the titration curve to determine the equivalence points for the unknown acid, the volumes at 50% of the equivalence points, Ka1, and Ka2 for the unknown acid. Because we recorded the pH at about 1 mL increments, we will need to do some estimating of pH values. When doing the estimating, a good approach is to average the known values on either side of the point you want to estimate. There will be some error in our readings, but it should be small enough for our purposes. (1pts) Select the unknown you used for this experiment. A Saved (2pts) Identify the second equivalence point on the titration curve. Use the two volume measurements where the largest change in pH occurs. Take the average of these two volumes to find where the equivalence occurs. What is the volume needed to reach the second equivalence point
