For this question, answer it on your work paper. In the box below, type “complete” when finished. Make sure to show all of your work. Consider the titration of the weak acid 100ml of 0.5M HA with a strong base 1.0M NaOH ka = 1.8 x 10-10 a) What is the pH at the equivalence point? b) What the pH when adding 70ml of NaOH to the flask? c) What would the pH be if 70ml of NaOH was added to a strong acid? d) Would the titration curves between titrating a weak acid and titrating a strong acid be the same? Explain. You can draw out the curves if you would like.

This box is to remind you that you should already have earned up to 32 points toward the Final Exam grade, based on your work on the Open Book Quiz on ethics theories. (If somehow you missed this, you will want to locate it in Modules and complete it right away.) This concludes your Final Exam. The numerical score you may see after you submit this quiz doesn’t yet include the points that will be added later for your essay/short answer questions (which I have to read and grade individually). Your exam should be fully graded by the end of the week, and you should be able to see your course grade then as well. Again, thank you for your good work this summer. I hope you have a safe and healthy break before the new semester begins.
