✓ 10- Consider a buffered solution containing CH3NH3Cl and CH3NH2. Which of the following statements concerning this solution is true? (ka for CH3NH3+=2.3 x 10-11) C. If (CH3NH2) < (CH3NH3CI), then the pH <3.36. B. If (CH3NH2) > [CH3NH3CI), then the pH is larger than the pka value. A. A solution consisting of 0.10 M CH3NH3Cl and 0.1 M CH3NH2 would have a higher buffering capacity than one containing 1.0 M CH3NH3Cl and 1.0 M CH3NH2 D. If (CH3NH2) = (CH3NH3CI), then the pH = 10.64 E. B and D are correct
