Acid-Base titration question
- Below are three usual errors students make during a titration lab. Explain how these errors will affect the calculation of the concentration of molar mass of the unknown acid. Be specific and detailed, otherwise, you will not get any credit.
- The student rinsed the burette with water but forgot to rinse with NaOH solution.
- The student dint added carefully the unknown acid to the Erlenmeyer flask.
- The student dint rinsed the flask with DI water and left a drop hanging in the burette as the titration was done.

known base which is NaOH that has a concentration of .100 M.
5. A student starts a titration without phenolphthalein in the Erlenmeyer flask. The student realizes the mistake and adds the phenolphthalein during the titration. Once the phenolphthalein is added, the solution in the Erlenmeyer flask remains colorless. Can the results of this titration be used? Concisely explain.

5. During the titration of an acid with a base, the sides of the Erlenmeyer flask are washed with distilled water. Do you think this rinsing will affect the outcome of the titration? Why or why not? 6. The approximate concentration of the NaOH solution you will prepare in Part A of this ex- periment is 0.12 M.

Question 6 (1 point) 1.681 g of an unknown diprotic acid are used to make a 100.00 mL solution. Then 25.00 mL of this solution is transferred to an Erlenmeyer flask and is titrated with 0.1047 M NaOH. The titration endpoint is reached after 0.00411 mol of NaOH is added using the burette. What is the molar mass of the diprotic acid? Provide your answer to the correct number of significant figures. Your Answer: Answer units
