Now you will add acid or base to the imidazole/HCl solution to see how well the buffer resists changes in pH. (a) You add 10.0 mL of 0.200 M HCI to 50.0 mL of buffer. What is the pH of the resulting solution? pH = 7.23 (b) You add 3.00 mL of 0.500 M NaOH to 30.0 mL of buffer. What is the pH of the resulting solution? pH = 8.13 (c) You add 15.0 mL of 0.200 M HCI to 10.0 mL of buffer. What is the pH of the resulting solution? pH=1.55 Answer 1: 7.23 Answer 2: 8.13
