Consider a buffer solution consisting of CH3NH3Cl and CH3NH₂. Which of the following statements are true concerning this solution? (Ka for CH3NH3+ = 2.3 × 10 -11). True If [CH3NH3+] < [CH3NH₂], then the [H+] is larger than the Ka value. ✓ If [CH3NH3+] = [CH3NH₂], then pH = 7.00. Adding more [CH3NH3+ to the initial buffer solution will increase the pH. If [CH3NH3+] >[CH3NH₂], then pH is larger than the pką value. ✓ A solution consisting of 0.1 M CH3NH3Cl and 0.1 M CH3NH₂ would be a more effective buffer than one containing 3 M CH3NH3Cl and 3 M CH3NH₂ ✓ If HCI were added to the initial buffer solution, then the [CH3NH3+] would increase.

Consider a buffer solution consisting of CH3NH3Cl and CH3NH₂. Which of the following statements are true concerning this solution? (ka for CH3NH3+ = 2.3 × 10 -11). True | If [CH3NH3+] < [CH3NH₂], then the [H+] is larger than the K₂ value. | If [CH3NH3+] = [CH3NH₂], then pH = 7.00. Adding more [CH3NH3+ to the initial buffer solution will increase the pH. ✓ If [CH3NH3+] >[CH3NH₂], then pH is larger than the pka value. A solution consisting of 0.1 M CH3NH3Cl and 0.1 M CH3NH₂ would be a more effective buffer than one containing 3 M CH3NH3Cl and 3 M CH3NH₂ ✓ If HCI were added to the initial buffer solution, then the [CH3NH3*] would increase.
