Acids and Bases – Titration of Vinegar – Level 3 11.89 mL of 0.470 M sodium hydroxide (NaOH) was needed to titrate a 9.98 mL sample of vinegar that was being tested for FDA approval. What is the weight percent of acetic acid in the vinegar sample? Given: Vinegar Solution Density = 1.005 g/mL Hint: Do not simply assume its going to be around 4-5%. You must calculate the answer.

Interpreting the Ferric Chloride Test in Synthesis of Aspirin – Yields and Reaction Reading – Level 3 In class, one of your fellow students asked what the reaction was that caused the color change of the solution.When the test is used on the appropriate conditions, a purple color is expected to appear. This purple color is due to the violet complex shown below. Using this information above and the knowledge from the lab/worksheet, solve for the expected yield of the hydrochloric acid (product) if given 6 grams of acetylsalicylic acid and 6 grams of iron chloride, all of which is mixed and dissolved in deionized water just like in the lab. Hint: Examine the reaction conditions closely, matching names and structures. Refer to your observations from this lab if necessary.
