Sketch the titration curve that will be obtained when 50 mL of 0.05 M glycine at pH 1.5 is titrated
with 0.05 M NAOH at 25°C on the graph provided below. In your graph, show (i) the position of
the initial pH of the solution before NaOH is added, (ii) the ½ equivalent point 1, (ii) the 1“
equivalent point, (v) the position and value of the pl (vi) the second ½equivalence point and (vii)
the endpoint of the titration. Remember to also indicate the volume of NaOH at these key points
your curve. Be as accurate as possible.
