Calculate and show how you calculated Keq for a, b, and c For each of the following solutions: (i) Enumerate all the possible Brønsted acids and Brønsted bases initially present; (ii) Determine which is the strongest acid and the strongest base; (iii) Write a balanced chemical equation for the reaction between the strongest acid and the strongest base; and (iv) Calculate Keq for this reaction. Use the data provided in the Ka or Kb tables in your textbook as needed. a. Sodium hydrogen sulfate, NaHSO4, and potassium cyanide, KCN, are dissolved in water. b. Ammonium acetate, [NH4][CH3CO2], is dissolved in water. c. Sodium hydrogen carbonate, NaHCO3, is dissolved in water. Please note that a species can be amphoteric and act as both an acid and a base.
