1. What is the molar ratio of base/salt is required to prepare a
buffer solution of 7.2? The pKb of the base is 6.5 at room
temperature.
2. What is the pH of a buffer solution containing 0.02 M boric
acid and 0.02 M sodium borate in 1000 ml of buffer solution? The
pKa of the boric acid is 6.4 x 10-10 at room temperature.
3. The molar solubility of sulfathiazole (pKa 7.2) is 0.001 M.
