The Ka of butanoic acid (C3H7COOH) is 1.5 × 10-5. You make a solution with initial concentrations of 7.5 × 10-3 M butanoic acid and 8.5 × 10-2 M sodium butanoate. Calculate the pH and the percent ionization of butanoic acid in this solution. *I will only award points if a solution is presented. What good does just the answer do for me?
