Your laboratory supervisor directs you to prepare 500.0 mL of a buffer with a pH of 9.40. You have available all the weak acids and bases listed in your textbook's appendix and the salts of those weak acids and bases. Describe how you could make this buffer.

    I don't have the appendix from your text. Look in that list, find a substance with a pKa of as close to 9.40 and go from there.

    This is not a question from the book, the appendic table is not needed, it is just an example of resources you may have.

    I got it DrBob222 thank you anyway!
