What is the pH when 55 mL of 0.050 M HF is combined with 125 mL of 0.10 M NaF. Ka = 6.8 x 10-4. Note: Assume that the changes in [HF] and [F-] are negligible. If no work is submitted for this problem, there will be a penalty of 50%. This means a correct answer for a 5 pt problem with no work is worth a maximum of 2.5 pts.
