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.

Answer 1

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.

Answer 2

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

Answer 3

I got it DrBob222 thank you anyway!
