1) Consider the following weak acids and their Ka values:
Acetic acid Ka = 1.8 x 10-5
Phosphoric acid Ka1 = 7.5 x 10-3
Hypochlorous acid Ka = 3.5 x 10-8

You are to prepare buffers at pH = 2.8, 4.5, and 7.5. In the 2nd column write the fomulas for the respective weak acid-conjugate base buffer system that is the best choice for each pH from the listed acids? Explain your reasoning
