Discussion Overview
The discussion revolves around the titration of a triprotic acid with a strong base (NaOH) to determine the molar mass of the acid. Participants explore the implications of reaching different equivalence points in the titration process and the calculations involved in determining the molar mass based on the titration data provided.
Discussion Character
- Homework-related
- Mathematical reasoning
- Debate/contested
Main Points Raised
- One participant expresses uncertainty about how to start the calculation for the molar mass after determining the grams of NaOH used.
- Another participant questions which equivalence point is being referred to, noting the significance of this in the context of a triprotic acid.
- A participant suggests calculating the number of moles of NaOH used and finding a relationship to the moles of triprotic acid to determine the molar mass.
- There is a correction regarding the calculation of grams of NaOH, with a suggestion that the correct value should be around 0.149 g instead of the previously calculated 120.430 g.
- One participant challenges the idea of subtracting from the total, indicating disagreement with that approach.
- A later post introduces the possibility that the titration reaches the third equivalence point, raising further questions about the implications for the calculations.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the correct approach to the problem, with multiple competing views on how to interpret the equivalence points and the calculations involved.
Contextual Notes
There are unresolved assumptions regarding the specific equivalence point being referenced and the calculations for grams and moles of NaOH, which may affect the determination of the molar mass of the acid.
