CH202 Postlab 08 Titration Curves (Postlab) SCHNELL ZACHARY EUGENE CH202, section 005, Fall 2008 Instructor: weiming zheng TA Web Assign Current Score: 25 out of 25 Due: Thursday, October 30, 2008 11:00 PM EDT The due date for this assignment is past. Your work can be viewed below, but no changes can be made. Request Extension 1. 1.4/1.4 points Select all that are true for a titration of 0.20 M KHP with 0.20 M HCl as the titrant as compared to your titration with 0.20 M NaOH as the titrant in lab. phenolphthalein would be an appropriate indicator the pH at the midpoint would be the same the pH at the equivalence point would be the same the initial pH would be the same the equivalence volume would be the same 2. 1.4/1.4 points Select all of the following that are benefits of a pH titration that is monitored using a pH electrode. the titration does not have to be stopped exactly at the equivalence point cheaper to run because no expensive equipment is needed the identity of the analyte can usually be determined from the pH at the midpoint
