C6:
Titration Curve for KHP
Objective:
Model a titration of a weak acid with a strong base.
You will learn about the
assumptions inherent in the calculations and also about the effects these assumptions
have on how well the experiment can be modeled.
You will learn how to attempt to
refine the model to improve agreement with experiment.
Part A
Due Tuesday, October 19
Develop a spreadsheet program to calculate the change of pH with volume of base
added for the theoretical titration of an acid with a strong base.
Calculate the titration
curve for the titration of KHP with NaOH described below, and graph your results.
For
your Lab 4 report you will do this model calculation for one of your own KHP titrations,
and then compare this model curve with your experiment results.
Thus, it will be
advantageous to write a flexible spreadsheet that will allow you to get new results simply
by entering initial volumes and formal concentrations.
Even though you will plot pH on the yaxis and volume of titrant on the xaxis,
