If a buffer solution is 0.130 M in a weak acid (K) = 7.2 x 10-5) and 0.580 M in its conjugate base, what is the pH? pH = A 1.50 L buffer solution consists of 0.328 M propanoic acid and 0.165 M sodium propanoate. Calculate the pH of the solution following the addition of 0.070 mol HCl. Assume that any contribution of the HCl to the volume of the solution is negligible. The K, of propanoic acid is 1.34...
