Question
This is all the information. I already answered a-d. The question is on the first picture: solution is around 50-60mL. What is the theoretical shift in pH if treated with 1mL of 1M HCl? What about when treated with 1mL of 1M NaOH?
Additional Requirement 24 hours before the lab you will be assigned a pH value and you will need to design the most appropriate buffer system that will give your assigned pH value. You are required to complete and understand Question 13 in Chapter 17 of Kotz et al. 1. 2. You must determine the following for your buffer system (showing your calculations and tabulating your data in Table 8b.1): a. The mole ratio of conjugate base to acid for your buffer system. b. The mole fraction of each component for your buffer system C. Assume that you have access to exactly 10 millimoles of the appropriate acid. Determine the moles of conjugate base you would have to generate from the original 10 millimoles of acid to attain the desired pH for your particular buffer system. d. Assuming you have access to 1 M NaOH, what volume of NaOH would have to be added to the 10 millimoles of acid to generate the appropriate amount of conjugate base? Page | 1
