How Is the Volume of Ethanoic Acid Determined from the Titration Graph?

Click For Summary
SUMMARY

The volume of ethanoic acid used in titrations is determined from the titration graph, specifically within the range of 25.5-26.5 mL, rather than the initially assumed 30 mL. This range corresponds to the point where the temperature stabilizes, indicating the endpoint of the titration. To accurately read the volume from the curve, one can draw two straight lines on the plot to identify their intersection, which signifies the volume of ethanoic acid used.

Homework Statement


upload_2019-1-12_11-18-42.png

the question asks for the concentration of ethanoic acid, therefore I need to find out the volume of ethanoic acid used during the titrations. I thought it would be 30mL because that's when the temperature reaches maximum. But the answer says that the volume should be in the range of 25.5-26.5, and I don't know how it is read from the curve. Thanks in advance!

The point at 25 is very close to the maximum already. The variations afterwards are probably just fluctuations or the mixture slowly returning to room temperature. You can draw two straight lines in the plot and see where they meet.
