Lab Questions 1. Suppose you dispense titrant until a very, very faint pink color persists and does not disappear. Explain whether or not more titrant is needed, and how you would proceed. 2. An air bubble is inadvertently left in the NaOH buret tip prior to a titration, and it exits during the titration. Explain how this affects the volume measurement and concentration calculation for NaOH in part A 3. Suppose some titrant liquid clings to the wall of the buret, and does not drain down during the titration. Explain how this affects the level of the meniscus and the final volume measurement. 4. Suppose one group left the cap off the container of slightly hygroscopic KHP before your group obtained it. Explain how and why your calculations of KHP, NaOH, and acid moles may be different from the actual moles of each. s. Suppose you rinse the analyte flask with boiled, deionized water during the titration as directed by the procedure, but you use a lot of water. Explain if, and how, this affects your moles of acid and base in the flask, and your concentration calculations.
