Suppose you need to prepare a buffer system with a pH = 5.30 in the laboratory. The available acids (in solid form) are the following: HX: Ka = 2.5 x 10^-3 HY: Ka = 4.8 x 10^-6 HZ: Ka = 3.2 x 10^-9 Which is the most suitable acid? Describe how to prepare a 1 L of the buffer solution with pH = 5.30 assuming all the salts of these acids are available in the lab.
