You find 5.00 g of an acid (C7H5O2H) and 5.00 g of a salt (KC7H5O2) in the lab and decide to prepare a 1.00 L buffer solution using these chemicals. Explain how to prepare a buffer at a pH of 4.0 with a maximum buffer capacity using the chemicals available. Ka = 6.46×10-5. Show all of your work and calculations and be sure to explain how many grams of each chemical should be used.
