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, (iii) the 1* equivalent point, (v) the position and value of the pl (vi) the second ½ equivalence point and (vii) the endpoint of the titration. Remember to also indicate the volume of NaOH at these key points in your curve. Be as accurate as possible.

![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 2 equivalent point 1, (iii) the 1*
equivalent point, (v) the position and value of the pl (vi) the second ½ equivalence point and (vii)
the endpoint of the titration. Remember to also indicate the volume of NaOH at these key points
in your curve. Be as accurate as possible.
pKal of glycine = 2.34, and pK2 of glycine = 9.60.
