Ammonia, NH3, is a weak base with a Kb value of 1.8105. The degree to which a weak base dissociates is given by the base-ionization constant, Kb. For the generic weak base, B B(aq)+H2O(l)BH+(aq)+OH(aq) Part A this constant is given by What is the pH of a 0.340M ammonia solution? Kb=[B][BH+][OH] Express your answer numerically to two decimal places. Strong bases will have a higher Kb value. Similarly, strong bases will have a higher percent ionization value. Percent ionization =[B]initial[OH]equilibrium100% Strong bases, for which Kb is very large, ionize completely pH= (100\%). For weak bases, the percent ionization changes with concentration. The more dilute the solution, the greater the percent ionization. Part B What is the percent ionization of ammonia at this concentration? Express your answer with the appropriate units
