In the study of biochemical processes, a common buffering agent is the weak base , (HOCH2)3CNH2(HOCH2)3CNH2, often abbreviated as TrisTris. At 25 ∘C∘C, TrisTris has a pKbpKb of 5.91. The hydrochloride of TrisTris is (HOCH2)3CNH3Cl(HOCH2)3CNH3Cl, which can be abbreviated as TrisHCl.
A) What volume of 10.0 M NaOH is needed to prepare a buffer with a pH of 7.79 using 31.52 g of TrisHCl?
B) The buffer from Part A is diluted to 1.00 L. To half of it (500. mL), you add 0.0300 mol of hydrogen ions without changing the volume. What is the pH of the final solution?
C) What additional volume of 10.0 M HCl would be needed to exhaust the remaining capacity of the buffer after the reaction described in Part B?
