Based on the table below: 1). create a titration curve of pH vs. volume NaOH (graph in in Excel).  Indicate on graph the location of each pKa (pka1, pKa2, pKaR) , first and second equivalence point and pI. Show all your calculations.  2). 1st derivative plot of ΔpH / Δvol NaOH an the y-axis and average vol NaOH on the x-axis (graph in Excel).  Highlight (label) the equivalence points Table 1.2 - Titration of an unknown amino acid with NaOH Vol. NaOH (mL) pH Avg.Vol. NaOH (mL) pH / Vol NaOH 0.00 2.12 0.5 0.02 1.00 2.14 1.5 -0.02 2.00 2.12 2.5 0.13 3.00 2.25 3.5 0.07 4.00 2.32 4.5 0.06 5.00 2.38 5.5 0.06 6.00 2.44 6.5 0.07 7.00 2.51 7.5 0.1 8.00 2.61 8.5 0.11 9.00 2.72 9.5 0.08 10.00 2.80 10.5 0.29 11.00 3.09 11.5 0.44 12.00 3.53 12.5 1.17 13.00 4.70 13.5 0.51 14.00 5.21 14.5 0.29 15.00 5.50 15.5 0.18 16.00 5.68…
