A student used a pH meter to collect data for the titration of an unknown concentration of propanoic acid with a 0.150 mol/L solution of sodium hydroxide. The data table from the investigation is shown in the table below.

Question
1. Enter the data from the table into a spreadsheet program. Use the program to plot the results, with pH on the
vertical axis and volume of base added on the horizontal axis.
**TIPS:
• If using excel, you want to create a scatter plot with smooth lines and markers. DO NOT create a line graph.
• If using google sheets, you can create a smooth line chart.
•
Make the plotted points large enough so that they are clearly visible.
Make sure you can see detail on your grid for accurate interpretation. For major gridlines, count by 1. Show minor gridlines.
• Include labels for each axis.
•
Provide a suitable and descriptive title.
•
A google search will help you with this if you are not familiar with using a spreadsheet to create a graph or how to properly
format. Or you can ask your teacher.
2. Print your graph or export it to a suitable computer program that you can draw on. It should take up the whole
page.
3. On your graph:
a. outline and shade the buffer region.
b. identify the pH range of an indicator suitable for this titration.
c. name two indicators that would have endpoints suitable for this titration.
4. The titration curve should show a steep change in pH near the equivalence point. Choose a point halfway
along the portion of rapid change on the graph. Label this the equivalence point and include the values of the
coordinates.
