The red line shows the average total charge on each molecule in solution (right axis), while the green, blue and yellow lines show the fraction of each of three differently ionized forms of 1b i) draw the structure of the green, red, yellow line and give the formal charge of each line ii) From the graph estimate the isoelectric point of 1b and explain how you arrived at your results? iii) Estimate the pka of the carboxylic acid group (-COOH) and ammonium group (-NH3*) in 1b and explain how you arrived at your result?
