Prepare a plot for the titration of a weak acid with a strong base by plotting the titration of 20.0 mL of 0.0329 M pyridinium chloride, C5H5NH+Cl- (aq), by 0.0257 M KOH. From the graph, determine
(a) The volume of titrant needed to reach the stoichiometric point
(b) The starting pH of the acid solution
(c) What is the pH at the stoichiometric point?
