This question concerns part 2 of the lab. Your target pH is still 5.40, and you are starting with 10.0 mL of 0.100 M sodium acetate solution. To create the buffer, you use a burette filled with 0.100 M HCI solution and dip a pH meter into the sodium acetate solution. You add HCI from the burette until the pH meter reads 5.40 exactly. How volume of HCI (in mL) should have been added from the burette at this point? Please note in real life the actual volume needed may differ from the "ideal" calculated value. Report your answer to two decimal places. Answer:

One student calibrated a 50-ml burette by using the mass of water delivered. The student used an analytical balance which was previously calibrated by STEEL (density = 7.8 g/mL). During calibration, the temperature of water was found to be 19.0.C. The density of water at this temperature is 0.9984 g/ml The results of the calibration by the student is shown in the table below: A B C D E Apparent burette reading,mL 10.05 20.04 30.08 40.07 49.98 Weight H2O delivered, g 10.03 20.09 30.05 40.02 49.83 Note: All masses in mentioned in this section are understood to be in grams and all volumes mentioned are understood to be in milliliters. 35.
