Questions:1. Why does the tip of your buret need to be free of air bubbles?2. Explain why the volume of water did not need to be exactly measured or recorded.3. Define the endpoint of a titration.4. What is a standard solution? Why is a standard solution necessary for titration?5. A student starts a titration without phenolphthalein in the Erlenmeyer flask. The studentrealizes the mistake and adds the phenolphthalein during the titration. Once thephenolphthalein is added, the solution in the Erlenmeyer flask remains colorless. Can theresults of this titration be used? Concisely explain.6. Write a balanced equation for the neutralization of hydrobromic acid with potassiumhydroxide.7. What is the molarity of a 12.46 mL sulfuric acid solution if 18.22 mL of 0.100 M potassiumhydroxide is required to reach the endpoint as indicated by a titration.43
