Consider a buffer solution comprised of HF and F-. The Ka of HF is 6.3 x 10-4. If the pH of the buffer solution is 3.64 and [HF] = 0.110 M, how many moles of F- are present? The volume of the buffer solution is 297 mL.
Consider a solution which is 0.10 M in HF and 0.15 M in KF. If 0.10 moles of NaOH is added to the solution, which of the following is true? The Ka for HF is 3.5 x 10-4 (at 25ºC) Group of answer choices The pH of the solution will not change. The buffer capacity of the solution will be exhausted. The pH of the solution will decrease. The Ka of HF will decrease.
If a solution of HF (Ka=6.8×10^−4) has a pH of 3.50, calculate the concentration of hydrofluoric acid. So far, I've made 5 incorrect attempts at the answer and have one attempt remaining. My answers were as follows: 0.00015, 1.5x10^-4, 1.5x10^-5, 0.001, and 0.00032 (This last answer prompted the website to tell me: "This value is the concentration of H+. This concentration and the Ka value can be used along with the equation for Ka to determine the initial concentration of...
