what is the pH of a buffer that is 0.76 Min HF and 0.98 M in NaF

1 answer

Substitute into the Henderson-Hasselbalch equation.
NaF is the base in that formula and HF is the acid. Post your work if you get stuck. You will need to look up Ka for HF. You will need pKa. You get that from pKa = -log Ka
