Chem II Lab- Titration of Vinegar with NaOH

Click For Summary
SUMMARY

The discussion centers on calculating the grams of acetic acid in vinegar using a molarity of 2.7 M. The molecular weight of acetic acid (H(C2H3O2)) is established as 60.06 g. The calculation performed yields 162.16 g of acetic acid per liter of vinegar, which is considered high for typical vinegar concentrations. The conversation also references the availability of concentrated acetic acid (Essigessenz) in Germany, indicating that while 2.7 M is strong, it is not impossible for certain vinegar products.

PREREQUISITES
  • Understanding of molarity and its calculation
  • Knowledge of molecular weight and its application in stoichiometry
  • Familiarity with titration techniques in chemistry
  • Basic grasp of acetic acid properties and concentrations
NEXT STEPS
  • Research the process of titration and its applications in acid-base chemistry
  • Learn about the properties and uses of acetic acid in various concentrations
  • Explore the concept of molarity and how it applies to different solutions
  • Investigate the safety and handling of concentrated acetic acid products like Essigessenz
USEFUL FOR

Chemistry students, laboratory technicians, and anyone involved in acid-base titration experiments or vinegar production and analysis.

Homework Statement



"Calculate the grams of acetic acid per liter of vinegar"


Homework Equations



Previous problem stated the multiply the average molarity of diluted vinegar times 10= 2.7 M

Vinegar (acetic acid)= H(C2H3O2) molecular weight= 60.06 g

The Attempt at a Solution



moles= M x L
2.7M x 1L = 2.7 moles
2.7 moles x 60.06 g= 162.16 g

This seems way too high. and i wasn't given anything really and it is driving me insane!

Thank you in advance for anyone who helps!

To the extent that you described your situation, the work and the result look good.

Note that you labeled the topic, "...Titration of Vinegar...". We may assume you were doing calculations to prepare to perform a titration.
 
2.7M acetic acid is about 16% - strong for vinegar, but not impossible.

In Germany in grocery stores you can buy Essigessenz which is basically just 70% acetic acid.
