Problem- Part A) What volume of 10.0 M NaOH is needed to prepare a buffer with pH of 7.79 using 31.52 g of TrisHCl?
Correct answer is 6.7 mL
Part B) The buffer from Part A is diluted to 1.00 L . To half of it 500mL you add 0.0300 mol of Hydrogen ions without changing the volume.
What is the pH of the final solution? (Answer should be in two decimal places)
