Exercise 1- Questions Question 1 1. If the manufacturer of the vinegar used in the experiment stated that the vinegar contained 5.0% acetic acid, what would the percent error between your result and the manufacturer's statement be? Show your work. B Question 2 1 B Question 3 B U 2. What challenges would you encounter with the titration if you had used apple cider vinegar or balsamic vinegar as the analyte instead of distilled white vinegar? !!! 1 III 15 Ti T₂ 111 7 L 3. How would your experimentally determined vinegar concentration have differed if the tip of the titrator was not filled with NaOH before the initial volume reading was recorded?

Question 4 4. How would your experimentally determined vinegar concentration have differed if you had over-titrated (added drops of NaOH to the analyte beyond the stoichiometric equivalence point)? B Question 5 1 U B 5. If a 7.0 mL sample of vinegar was titrated to the stoichiometric equivalence point with 7.5 mL of 1.5M NaOH, what is the mass percent of CH3COOH in the vinegar sample? Show your work. T² T₂ 1 Question 6 B T 6. Why is it important to do multiple trials of a titration, instead of only one trial? 1 U T THE 0 Word(s) 13 Ti T! 0 Word(s) 0 Word(s)
