a. Give the general Henderson-Hasselbalch equation and sketch the plot it describes (pH against amount of NaOH added to a weak acid). On your curve label the pKa for the weak acid, and indicate the region in which the buffering capacity of the system is greatest.
b.Draw the titration curve for a weak acid, HA, whose pKa is 3.2. Label the axes properly. Indicate with an arrow where on the curve the ratio of salt (A-) to acid (HA) is 3:1. What is the pH at this
Draw a titration curve for both of these peptides. Be sure to label the axes properly, indicate the pKa values, the equivalence points and the buffering regions
