SUMMARY
The discussion focuses on the titration of a 0.307g sample of an unknown triprotic acid using 35.2 mL of 0.106 M NaOH to determine its molar mass. Participants clarify that the calculation must consider the third equivalence point due to the triprotic nature of the acid. The correct approach involves calculating the moles of NaOH used and relating it to the moles of the triprotic acid to find the molar mass. The final calculation yields a molar mass based on the stoichiometry of the reaction.
