You are asked to reduce the pH of the 0.300 L of buffer solution in Example 17-5
Question:
You are asked to reduce the pH of the 0.300 L of buffer solution in Example 17-5 from 5.09 to 5.00. How many milliliters of which of these solutions would you use: 0.100 M NaCl, 0.150 M HCl, 0.100 M NaCH3COO, 0.125 M NaOH? Explain your reasoning.
Example 17-5
What mass of NaCH3COO must be dissolved in 0.300 L of 0.25 M CH3COOH to produce a solution with pH = 5.09? Assume that the solution volume remains constant at 0.300 L.

Step by Step Answer:
To reduce the pH of the buffer solution from 509 to 500 you need to add a small amount of a strong acid to shift the equilibrium toward the undissocia...View the full answer
