CRITICAL THINKING QUESTIONS: Answer the following questions in your lab notebook (be sure to show work for any calculations): 1. What is a diprotic acid? Give an example not found in the below text for this investigation. 2. Give the balanced chemical reaction for the titration of the above diprotic acid with potassium hydroxide to the first equivalence point. Give the balanced chemical reaction for the titration of the above diprotic acid with potassium hydroxide to the second equivalence point. 3. When titrating 50.0 mL of 0.10 M H₂SO4 with 0.10 M NaOH, how many mL of NaOH will you have added to reach the 1st equivalence point? Second equivalence point? 4. A student completes a titration of an unknown diprotic acid. In this experiment, 0.79 g of the acid is dissolved in 250.0 mL of water. It requires 13.48 mL of 1.0 M NaOH to reach the second equivalence point. What is the molar mass of the acid?
