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...

help with this question
Consider a 0.211 L solution of the amino acid aspartic acid (0.631 M), which has an alpha carboxylic acid group (pka = 2.10), an alpha amine group (pka = 9.82), and a carboxylic acid group in the side chain (pka = 3.86). If the titration is started at a very low pH, how many liters of 2.25 M NaOH would you need to add to reach the isoelectric point of the amino acid? Give your answer...
