Eаch оf three beаkers cоntаins 25.0 mL оf a 0.100 M solution of HCl, NH3 , or NH4Cl , as shown below. Each solution is at 25°C. (a) Determine the pH of the solution in Beaker 1. Justify your answer. (1 point)(b) In beaker 2, the reaction NH3(aq) + H2O(l) NH4+(aq) + OH-(aq). The Kb for NH3(aq) is 1.8 x 10-5 at 25°C. (i) Write the Kb expression for the reaction of NH3(aq) with H2O(l). (1 point) (ii) Calculate the [OH-] in the solution in beaker 2. (2 points)(c) In Beaker 3, the reaction NH4+(aq) + H2O(l) NH3(aq) + H3O+(aq) occurs. (i) Calculate the value of Ka for NH4+(aq) at 25°C. (1 point) (ii) The contents of Beaker 2 are poured into Beaker 3 and the resulting solution is stirred. Assume that volumes are additive. Calculate the pH of the resulting solution. (2 point)
