1. A student performed the titration as in this experiment. He transferred a 2.00 mL sample of the
acid into a flask, diluted it with water, and then began to add sodium hydroxide solution from the
buret. After adding 50 mL of NaOH solution, the sample in the flask still had not turned pink.
What error did the student make?
2. Compare your percentage of HCI to the manufacturer's percentage for the toilet bowl cleaner.
Were your results close? What might account for any differences?
