1. You wish to prepare an HC2H3O2 buffer with a pH of 5.44. If the pKa of this is 4.74, what ratio of C2H3O2-/HC2H3O2 must you use?

2. Calculate the pH of a buffer that is 0.058 M HF and 0.058 M LiF.
The Ka for HF is 3.5 x 10^-4

3. Calculate the pH of a buffer that is 0.158 M HClO and 0.099 M NaClO.
The Ka for HClO is 2.9 x 10^-8.

4. Calculate the pH of a buffer that is 0.105 M HC2H3O2 and 0.146 M KC2H3O2.
The Ka for HC2H3O2 is 1.8 x 10^-5
