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).
True/ False A solution consisting of 0.25 M CH3NH3Cl and 0.25 M CH3NH2 would be a more effective buffer than one containing 2.5 M CH3NH3Cl and 2.5 M CH3NH2
True/ False If [CH3NH3+] > [CH3NH2], then the [H+] is smaller than the Ka value.
True False Adding more [CH3NH3+] to the initial buffer solution will decrease the pH.
True/ False If HCl were added to the initial buffer solution, then the [CH3NH3+] would increase.
True/ False If [CH3NH3+] = [CH3NH2], then pH = 7.00.
True/ False If [CH3NH3+] >[CH3NH2], then pH is larger than the pKa value.
