88c.  [Tutorial: Titration stoichiometry] This question will walk you through the steps of calculating the volume of titrant required to reach the endpoint based on the volume and concentration of analyte. Consider the standardization of NaOH by titration with C₆H₈O₇ according to the following chemical reaction: 3 NaOH(aq) + C₆H₈O₇(aq) ⇌ Na₃C₆H₅O₇(aq) + 3 H₂O(l) Step 3: Calculate the volume of titrant required to reach the endpoint. Calculate the volume in mL of a 0.200 M NaOH solution needed to neutralize 345 mL of 0.0333 M C₆H₈O₇ standard solution.   88d. Based on the fact that NaOH is a strong base and C6H807 is a weak acid, how would you describe the pH of the solution at the endpoint, where moles of base = 3 times the moles of acid?
