Consider the titration of a 24.0 mL sample of .175 M of CH3NH2 with .155 M HBr. Determing each of the following:
A. initial pH
B. the volume of added acid required to reach the equivalence point
C. pH at 5.0 mL of added acid
D. pH at one-half of the equivalence point
E. pH at eq. point
F. the pH after adding 5.0 mL of acid beyond the equivalence point
