Prelab Assignment Acid-Base Titration Acetic Acid Content of Vinegar Read the entire lab. Answer the following questions after reading through the lab. 1. Complete and balance the following reactions: a. HCI + NaOH - b. H2SO4 + NaOH 2. Calculate the mass of NaOH required to make I L of a 0.843 M NaOH solution. 3. Assume you are titrating 10 mL of vinegar that is 5% acetic acid, CHCOOH, by weight with 0.843 M NaOH. How many mL of 0.843 M NaOH will be required to reach the equivalence point? Assume the density of vinegar is 1 g/mL. 4. Briefly describe how you will know that you have reached the endpoint of your titration in this lab. In other words, exactly what will you see happen as you reach the end point of your titration?
