1. Click on the Investigation 1 tab at the top of the page.
1. Describe the effect of adjusting the initial [analyte] on the titration curve using the [titrant] = initial [analyte] setting.
2. Describe the effect of adjusting the initial [analyte] on the titration curve after you deselect the [titrant] = initial [analyte] setting.
3. Describe the effect of adjusting the analyte initial volume keeping all other variables the same.
4. Set the initial [analyte] and [titrant] = 0.10 M, and initial volume = 50.0 mL. Determine which indicators would be effective, with minimal titration error, for determination of the end point.
5. Now select strong base for the analyte, and adjust the variables to see how the titration curve varies.
2. Click on the Investigation 2 tab at the top of the page.
1. Describe the effect of changing the pKa of the weak acid.
2. Describe the effect of adjusting the initial [analyte] on the titration curve using the [titrant] = initial [analyte] setting.
3. Describe the effect of adjusting the initial [analyte] on the titration curve after you deselect the [titrant] = initial [analyte] setting.
4. Describe the effect of adjusting the analyte initial volume keeping all other variables the same.
5. Set the pKa = 5, the initial [analyte] and [titrant] = 0.10 M, and initial volume = 50.0 mL. Determine which indicators would be effective, with minimal titration error, for determination of the end point.
6. Now select weak base for the analyte, and adjust the variables to see how the titration curve and indicator selection varies.
7. You are given a 5.0 mM solution of 2,4-dinitrophenol (pKa = 4.114). Design a titration for which you can observe the end point within a 50 mL titrant range.  Select an initial [analyte], initial analyte volume, [titrant], and indicator.
3. Click on the Investigation 3 tab at the top of the page.
1. Use the module to help you design a titration for maleic acid (cis-butenedioic acid) for which you can observe both end points within a 50 mL titrant range. Select an initial [analyte], initial analyte volume, [titrant], and an indicator for each of the 2 end points.
