Titration Curve for a Polyprotic Acid Titration Curve for a Polyprotic AcidNAME:________________________________________ PERIOD:___________PrelabShow Calculations.1. For the titration of 20.0 ml of 0.100M maleic acid with 0.100M NaOH, using a Ka1 of 1.4 x 10-2 and Ka2 = 8.6×10-7, calculate the pH:a. Initially (0 ml of NaOH added):b. At the first half equivalence point:c. At the first equivalence point:d..
