The pK, value for HF is 3.14. Would a buffer prepared from HF and NaF with a pH of 5.14 be considered to be an effective buffer? A buffer in which the mole ratio of NaF to HF is 1.7 has a pH of 3.36. Would this buffer solution have a greater capacity for added acid (H307) or added base (OH)? added acid added base Submit Answer Retry Entire Group 9 more group attempts remaining
