Reading volume titrated from graph

In summary, the question is asking for the concentration of ethanoic acid and the volume of ethanoic acid used during titrations. The temperature reaches its maximum at 30mL, but the answer suggests a volume range of 25.5-26.5, which is unclear from the curve. There may be fluctuations or the mixture may be returning to room temperature. Drawing two straight lines on the plot can help determine where they meet.

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.

1. What is reading volume titrated from graph?

Reading volume titrated from graph is a method used in chemistry to determine the volume of a solution needed to react completely with a known volume of another solution. This is typically done by plotting a graph of the volume of the solution being added (known as the titrant) against the pH or another property of the solution being reacted with (known as the analyte).

2. How is reading volume titrated from graph performed?

To perform reading volume titrated from graph, a known volume of the titrant solution is added gradually to the analyte solution while measuring the pH or other property. This data is then plotted on a graph, and the volume of the titrant needed to reach the equivalence point (where the reaction is complete) can be read from the graph.

3. What is the significance of reading volume titrated from graph?

Reading volume titrated from graph is important because it allows scientists to accurately determine the concentration of a solution. This is useful in many areas of chemistry, such as in determining the strength of an acid or base, or in analyzing the purity of a substance.

4. Are there any limitations to reading volume titrated from graph?

Yes, there are some limitations to reading volume titrated from graph. This method assumes that the reaction being studied is a simple acid-base reaction and that the reaction proceeds to completion. It also requires precise measurements and may be affected by factors such as temperature and the presence of impurities in the solutions.

5. How can reading volume titrated from graph be used in real-world applications?

Reading volume titrated from graph is commonly used in industries such as pharmaceuticals, food and beverage, and environmental testing. It can also be used in educational settings to teach students about acid-base reactions and the use of titration in chemistry experiments.
