Ammonia is a convenient buffer system in the slightly basic range. (a) What is the pH of a buffer solution containing 39 g of NH4Cl dissolved in 1.00 L of 0.940 M NH3? pH = (b) How many moles of acid are required to change the pH of this solution by 0.01 pH units? mol (c) Suppose 5.6 mL of 10.5 M HCI solution is added to 230 mL of the solution of Part (a). Calculate the new pH. pH=
