Question

Please give explanation.

Consider the titration of 100.0 mL of 0.200 M CH₃NH₂ by 0.100 M HCl.
For each volume of HCl added, decide which of the components is a major species after the HCl has reacted completely.
K_b for CH₃NH₂ = 4.4 x 10^-4.

200.00 mL HCL added    yes no  H+ yes no  H2O yes no  Cl- yes no  CH3NH2 yes no  CH3NH3+

300.00 mL HCL added:

yes no  H⁺
yes no  H₂O
yes no  Cl^-
yes no  CH₃NH₂
yes no  CH₃NH₃⁺

Calculate the pH at the equivalence point for this titration?

At what volume of HCl added in this titration does the pH = 10.64? Express your answer in mL and include the units in your answer?
