Answer the following questions: 1. Use ChemDraw to draw the structures for: A. Acetic acid (Ethanoic acid) B. Benzoic acid 2. Why did acetic acid have an odor but benzoic acid did not? 3. Why did the acetic acid odor disappear after the addition of NaOH? Draw a reaction as part of your answer. 4. Why did the acetic acid odor reappear after the addition of HCI? Draw a reaction as part of your answer. 5. Write the reaction for the interaction between acetic acid and sodium bicarbonate. 6. Compute the average percent acetic acid in your vinegar sample. Average % acetic acid Value on label of bottle
Sample Odor Initially Solubility Litmus Odor Observations after NaOH Solubility Litmus Odor Observations after HCI Solubility Litmus Acetic Acid No odor Soluble Acidic No odor Soluble Basic No odor to us, but some say its sour. Soluble Acidic Benzoic Acid No odor Not soluble Acidic No odor Soluble Less Acidic No odor to us, but some say its sour Soluble Acidic Sodium Bicarbonate Test Strong Vinegar smell, it is soluble and test with litmus acid. List your observations here:
