The ammonia/ammonium buffer system is used to optimize polymerase chain reactions (PCR) used in DNA studies. The equilibrium for this buffer can be written as NH4 + (aq) ? H + (aq) + NH3 (aq) Calculate the pH of a buffer that contains 0.045 M ammonium chloride and 0.095 M ammonia. The Ka of ammonium is 5.6*10?10. Express your answer using two decimal places.
