Discussion Overview

The discussion revolves around two questions related to a lab experiment involving acetic acid. The first question examines a claim about gender differences in color vision based on the acetic acid concentrations reported by two students. The second question seeks assistance with calculations related to the mass percentage of undiluted acetic acid based on experimental data.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • Some participants suggest that if the claim about women having better color vision is true, then the student with the higher concentration (4.8%) might be female, as they could differentiate colors more accurately.
  • Another participant provides a calculation method for determining the mass percentage of undiluted acetic acid, indicating that the mass of vinegar can be calculated as the difference between the mass of the flask and the mass of the flask with vinegar.
  • It is noted that the millimole amount of NaOH can be calculated using the concentration and volume delivered, and that this can be used to find the mass of undiluted acetic acid by relating it to the molar mass of the compound.
  • One participant expresses uncertainty about the question's framing and the reasoning behind the gender-color vision claim.

Areas of Agreement / Disagreement

Participants express differing views on the interpretation of the color vision claim and its implications for the students' results. The calculation methods proposed are not universally agreed upon, and the discussion remains unresolved regarding the gender implications and the calculation approach.

Contextual Notes

There are limitations in the assumptions made regarding the relationship between gender and color vision, as well as the lack of provided formulas for the calculations, which may affect the clarity of the discussion.

Who May Find This Useful

This discussion may be useful for students or individuals interested in experimental chemistry, particularly those exploring the properties of acetic acid and related calculations, as well as those examining gender differences in sensory perception.

Had a lab few days ago and a question was presented:

[q]Some people claim that women possesses better color vision than men. Suppose ths is true. Two people perform this experiment and their results are as follows:

Student1: Acetic Acid Concentration - 4.5%
Student2: Acetic Acid Concentration - 4.8%

Based on the gender claim which student is male and which is female? Explain your reasoning.[/q]

:rolleyes: I am not exactly sure how to answer it. Can anyone help? :rolleyes:

Second:

I have the following results from my experiment after three trials: Mass of Erlenmeyer flask=A, Mass of flask and vinegar=B, mass of vinegar=C, initial volume of buret=D, final volume of buret=E, volume of NaOH delivered=F, and concentration of NaOH (mol/L) on bottle=G. I am asked to find Mass % of undiluted acetic acid and average mass % of undiluted acetic acid. We weren't given any formulas on how to determine this. Does anyone know what I would do in this case?

If your first question involves the use of vinegar, then the first one should be female, I think.

About your calculations, C is A-B, and F is E-D. The millimole amount of NaOH is G*F. The mass of undiluted acetic acid can be found my equalizing the millimole of NaOH and then multiplying with the molar mass of compound (C=12, H=1, O=16 g/mol).

maybe the student 2 is female because the student was able to diferenciate between the colors of the pH indicator used more accuarly than the first student. 4.5% could just be an estimation that the percentage is somewhere between 4 and 5, but 4.8% is a seemimgly more precise responce. I don't like way the question is given.
 
Hmm, a nice approach indeed. I haven't thought this through. Congrats.
