1. You are asked to prepare a buffered solution at a pH of 4.30 using the following acids and its potassium salt. What ratio of [HA] / [A- ] is required for each system?
a) Benzoic acid (C7H6O2, Ka = 6.4 x 10-5)
b) Hypochlorous acid (HClO; Ka = 3.5 x 10-8)
c) Which system would you choose to prepare the most effective buffering system? Explain.
d) For the system you chose, what mass (in grams) of all the necessary components do you need to weigh out in order to make a 2.00-L buffered solution? Assume no significant volume changes by the addition of the solid components
