The four beakers above each contain 100.-mL of different solutions of similar concentrations.
(a) The Kb for ammonia is 1.8 x 10^-5
(i) Which beaker is most likely to contain NH3(aq)? Provide a chemical equation to explain your answer.
(ii) Calculate the molarity of the solution in the beaker that you chose for (i).
(b) If the contents of beakers 3 and 4 are poured together and mixed thoroughly, what will be the resulting pH?
(c) Explain how it is possible that beakers 1 and 4 are acids with equal molarities.
