I don't know if it is possible, but I have to make a solution of acetic acid with a pH of 4 and a volume of 250 mL. I have 500 mL of acetic acid 10% and I need to add a certain amount of this acetic acid to the water to have this pH. I was wondering what are the quantities of water and acetic acid I need to "mix" together. Thank you !

Which of the following combinations of chemicals makes a buffer? Mark all that apply. (Identifying solutions as buffers on a quiz or exam is a critical skill. For this chapter, many problems ask you to find the pH of a solution. The challenge is classifying the solution appropriately, and then selecting the right approach to finding its pH.)
