On your first day working in a laboratory, you are told to make up 1 Liter of a 0.5 Molar Tris solution with a pH of 7.4. You measure out the appropriate amount of Tris base and dissolve it in water. You then measure the pH and find out that it has an initial pH of 11. You add some concentrated HCl, and the pH begins to drop. However, as you approach the target pH, you find that you need to add large amounts of HCl to lower the pH even a small amount.
