AP Chemistry 4.6 A Identify the Equivalence Point in a Titration Based on the Amounts of the Titrant and Analyte Assuming the Questions

The student used a 50.0 mL buret to add the $\mathrm{KMnO}_{4}(a q)$ to the $\mathrm{H}_{2} \mathrm{C}_{2} \mathrm{O}_{4}(a q)$ until a faint lavender color was observed in the flask, an indication that the end point of the titration had been reached. The initial and final volume readings of the solution in the buret are shown below. Write down the initial reading and the final reading and use them to determine the volume of $\mathrm{KMnO}_{4}(a q)$ that was added during the titration.

The student proposes to perform another titration using a 0.139 g sample of $\mathrm{H}_{2} \mathrm{C}_{2} \mathrm{O}_{4}$, but this time using $0.00143 M \mathrm{KMnO}_{4}(a q)$ in the buret. Would this titrant concentration be a reasonable choice to use if the student followed the same procedure and used the same equipment as before? Justify your response.
