The pH titration of 20.0mL of 0.231M Difluoropyrrole and 0.462 M hydrobomic acid is going to be run at the UNAC labs. In order to test the validity of the titration you have been asked to predict the following five key points on the pH plot in order to test the equipment. (a). pH before the start of the titration (b). pH after the addition of 3.00 mL of HBr (c). pH at the half titration point (d) pH at the equivalence point (e) pH at 0.50mL after the equivalence
