- Click on the Investigation 1 tab at the top of the page.
- Describe the effect of adjusting the initial [analyte] on the titration curve using the [titrant] = initial [analyte] setting.
- Describe the effect of adjusting the initial [analyte] on the titration curve after you deselect the [titrant] = initial [analyte] setting.
- Describe the effect of adjusting the analyte initial volume keeping all other variables the same.
- 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.
- Now select strong base for the analyte, and adjust the variables to see how the titration curve varies.
- Click on the Investigation 2 tab at the top of the page.
- Describe the effect of changing the pKa of the weak acid.
- Describe the effect of adjusting the initial [analyte] on the titration curve using the [titrant] = initial [analyte] setting.
- Describe the effect of adjusting the initial [analyte] on the titration curve after you deselect the [titrant] = initial [analyte] setting.
- Describe the effect of adjusting the analyte initial volume keeping all other variables the same.
- 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.
- Now select weak base for the analyte, and adjust the variables to see how the titration curve and indicator selection varies.
- 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.
- Click on the Investigation 3 tab at the top of the page.
- 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.
