Question

The R group of glutamic acid is ––CH2CH2COOH (pKa = 4.07). Sketch the titration
of the sidechain of a 15.00 mL of a 0.350 M solution of glutamic acid with 0.400 M NaOH
solution.
a). Calculate Ka from the pKa.
b). Calculate [H+], [OH-], pH and pOH at 0 mL of NaOH added.
c). How many mL of 0.400 M NaOH are needed to get to the endpoint?
d). What is the pH at the endpoint?
e). How many mLs is the ½ equivalent point? What is the pH at this point?
f). Calculate the pH after 5.00 mL of 0.400 M NaOH is added.
g). Calculate [H+], [OH-], pH and pOH after 25 mL of 0.400 M NaOH is added.
h). sketch the titration curve and label all labeling each point from (a-f) above including the ½
equivalence point.
