When a small amount of acid is added to a non-buffered solution, there is a large change in pH. Calculate the pH when 21.7 mL of 0.0028 M HCI is added to 100.0 mL of pure water. Comment and hint in the general feedback. Answer: 3.216 Note, less moles of acid are added in this example than in the following buffered example. Yet, you will see that the pH change in the buffered solution is smaller. (Hint, remember to use the total volume in your pH calculation.)
