im a hungry hippo who needs his food who needs his lunch. All my hungry hippo friends eat to live and live to munch. ... thAcid Base Titration II Introduction: In this experiment the titration of two unknown acids was performed. A monoprotic and diprotic acid were titrated. ... The data used to determine these unknowns was derived using a pH meter and the titration of the acids. ... Molecular weights of the acids were determined using the equation: N / M = molecular weight N = density of unknown acid x volume of unknown acid M = vol. of NaOH needed to reach Ep x molarity of NaOH solution Monoprotic Equations pKa = ½ equivalence point (Ep) Diprotic Equations pKa2 = (Ep2 / 4) x 3 pKa1 = ½ Ep1 Ep1 = Ep2 / 2 Materials: 50 mL Buret pH meter 25 mL sample of Monoprotic acid 25 mL sample of Diprotic acid 0.2 M NaOH solution 10 mL Volumetric pipet Procedure: The goal of this experiment was to determine the identity of an unknown acid with the use of a pH meter and a titration set up. |
