What is the pH of a solution containing 0.400 M of formic acid and 1.00 M sodium formate? (pKa = 3.744)
Added by Felipe S.
Step 1
This is a buffer solution, and we can use the Henderson-Hasselbalch equation to calculate the pH of the solution. The Henderson-Hasselbalch equation is: pH = pKa + log([A-]/[HA]), where [A-] is the concentration of the base (sodium formate) and [HA] is the Show more…
