Draw an approximation for the titration curve of glutamic acid which is the non-ionized or protonated form of glutamate. Make sure to label the axis. Clearly label each pKa on the graph (Hint: it may help you to connect the pK to the x and y axis, but not required). What is the Isoelectric point? Define the term isoelectric point, calculate and label the point on the graph. Draw the major species of glutamic acid with appropriate formal charges at the given pHs: pH<2, pH between each pKa,, pH~7, pH>10. Label which of the species is the zwitterion form.
Please follow the instructions for a thumbs up.

Draw the titration curve for the titration of 20 mL of a 0.12 M solution of glutamate (carboxylic acid pKa = 2.19, amino pKa = 9.67, you need to know the pKa for the R group) with 0.10 M sodium hydroxide. Clearly label the axes of your graph (pH vs mL of NaOH added.) Be sure to include pH values and volumes for the following: Start of the titration (no sodium hydroxide added), the pH at the volume that is...
