Designing a buffer solution with a specific pH In this activity you will be using the virtual lab to create 100ml of a buffer solution that has a pH of 9.26M The virtual lab stockroom has a number of 0.IM weak acids and conjugate bases to help you in this process. When you have completed making your buffer solution, use the form at the bottom of the page to check your answer. How many milliliters of each solution did you use to make the your buffer? (please use three significant figures for your answer) mL of acid: and mL of base: Chec
