Each of three beakers contains 25.0 mL of a 0.100 M solution of HCl, NH3 , or NH4Cl, as shown above. Each solution is at 25°C.
(a) Determine the pH of the solution in beaker 1. Justify your answer.
(b) In beaker 2, the reaction NH3(aq) + H2O(l) ? NH4(aq) + OH(aq) occurs. The value of Kb for
?5 NH3(aq) is 1.8 × 10 at 25°C.
(i) Write the Kb expression for the reaction of NH3(aq) with H2O(l).
- (ii) Calculate the [OH] in the solution in beaker 2.
(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.
+++-
(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.
