Answer both questions regarding Acids and Bases. After adding 50 mL of NaOH solution, the sample in the flask still had not turned pink. What error did the student make? and then, compare your percentage of HCI to the manufacturer’s percentage for the toilet bowl cleaner. We’re your results close? What might account for any differences? (Use the second photo for reference)
