Consider a buffered solution containing CH3NH3Cl and CH3NH2.
Which of the following statements are true concerning this
solution? (Ka for CH3NH3+ = 2.2 × 10-11). (Select all that
apply.)
If [CH3NH2] > [CH3NH3+], then pH is larger than the pKa
value.
If NaOH were added to the initial buffered solution, then the
[CH3NH2] would increase.
If [CH3NH2] = [CH3NH3+], then pH = 3.36
If [CH3NH2] < [CH3NH3+], then pH is larger than the pKa
value.
A solution consisting of 2.5...
