Consider a buffer made from a solution of HF to which has been added NaF.
The Ka of HF is 7.20 x 10⁻⁴. Given what you know about the Henderson-Hasselbalch equation determine if each of the following statements is true or false:
(1) This specific system could be used to buffer a solution at a pH of 3.0.
(2) When [HF] = [F^-] = 1.0 M, the buffer will resist pH change better than if [HF] = [F^-] = 0.10 M.
(3) When [HF] = [F^-], the pH of the buffer will always be 3.14.
(4) HF is the ^''HA^'' species in the Henderson-Hasselbalct, equation.
