Question

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? The buffer from Part A is diluted to 1.00 L. To half of it (500 mL), you add 0.0150 mol of hydrogen ions without changing the volume. What is the pH of the final solution? Express your answer numerically to two decimal places. Part 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?

Step 1

First, we need to find the moles of TrisHCl. The molecular weight of TrisHCl is approximately 157.6 g/mol. So, moles of TrisHCl = 31.52 g / 157.6 g/mol = 0.2 mol. Show more…
