Question
Being such a great lab partner, you have been tasked with the job of recording the data from your pH titrations. You were busy writing the data down (and graphing it as you go, because you ALWAYS graph a titration as you go!). The titration was one of 50 mL glycine (50 mM) vs NaOH (50 mM). In the haste to graph it, you realize too late that the axis have no labels, and no data points on it.
Your unscrupulous lab partners are insisting that you, as the smartest member, cheat a little and put all the data points that matter on the graph. You know can look up the Ka values for glycine, and that you know enough about the pH curve that you can figure out where all the end points are.
Fill in the end points (volume), equivalence points (volume and pH) using data you find online for glycine. Put a circle around any buffer regions.
