A 1.00L buffer solution is 0.250M HF and 0.250M LiF. Calculate the pH of the solution after the addition of 0.150 moles of solid LiOH.  Assume no volume change upon addition of the LiOH.  Ka for HF = 6.8 x 10-4 Equations: pH = -log[H3O+] pOH = -log[OH-] pH + pOH = 14.00 Kw = 1 x 1014 at 25oC Kw = Ka x Kb = [H3O+][OH-] pKa = -log Ka pH = pKa + log
