A word to the wise. Do NOT (that's NOT) think 0.1 m HOAc is the same as 0.1 M HOAc. 0.1 m is 0.1 MOLAL while 0.1 M is 0.1 MOLAR. They are NOT the same.
Use the Henderson-Hasselbalch equation.
pH = pKa + log [(base)/(acid)]
base = NaOAc; acid = HOAc.
What is the pH of a solution by dissolving 8.00 mmol of NaOAC in 200 mL of 0.100 m HOAC. (you need the pka for acetic acid)
