6. Consider the weak acid formic acid, for which K₂ = 1.8x104. a. What is the pH of a formic acid/sodium formate solution in which [formic acid] = 20 mM and [formate] = 15 mM? b. What is the pH of a formic acid/sodium formate solution in which [formic acid] = 20 mM and [formate] = 20 mM? c. If you add 3 mM HCI to the solution in part a, what is the new pH? d. If you add 3 mM HCI to the solution in part b, what is the new pH? e. Which of the two
solutions has better buffering capacity? Briefly explain why.
