1. How many grams of sodium lactate, NaC3H5O3, should be added to 1.00 L of 0.150 M lactic acid, HC3H5O3, to form a buffer solution with a pH of 3.90? (Ka = 1.4 × 10-4 for lactic acid)

2. What is the pH of the a buffer solution containing 0.10 moles of acetic acid and 0.13 moles of sodium acetate in 1.0 L after adding 0.02 moles of KOH?

3. What will the pH be if 0.0100 mol HA (pKa = 2.00) and 0.0100 mol A- are mixed together to make a 1.00 L solution?
