Preparing Buffer Solutions: Calculating the Volume of Weak Base Needed Use the table of K values given with this problem to choose the best weak base to start from for making a buffer that holds the pH of the solution at 9.70. Make your selection so that you maximize the capacity of the buffer. Assume that you want to make 100 mL of a buffer and you have already added enough of the conjugate acid salt to make the final...
