Consider a buffer solution consisting of CH3NH3Cl and CH3NH2. Which of the following statements are true concerning this solution? (Ka for CH3NH3+ = 2.3 x 10-11). False If [CH3NH3*]> [CH3NH₂], then the [H*] is larger than the K₂ value. Adding more [CH3NH3+] to the initial buffer solution will decrease the pH. False A solution consisting of 0.25 M CH3NH3Cl and 0.25 M CH3NH₂ would be a more effective buffer than one containing 2 M CH3NH3Cl and 2 M CH3NH2 False If [CH3NH3+] <[CH3NH₂], then pH is smaller than the pką value. True True If HCI were added to the initial buffer solution, then the [CH3NH3*] would decrease. False If [CH3NH3+] = [CH3NH2], then pH = 7.00.

One of the most challenging parts of solving acidbase problems is writing out the correct equation. When a strong acid or a strong base is added to solutions, they are great at what they do, and we always react them first. If a strong acid is added to a buffer, what reacts with the H+ from the strong acid and what are the products? If a strong base is added to a buffer, what reacts with the OH from the strong base and what are the products? Problems involving the reaction of a strong acid or strong base are assumed to be stoichiometry problems and not equilibrium problems. What is assumed when a strong acid or strong base reacts to make it a stoichiometry problem?
