Consider the titration of a 25.0 âmL sample of 0.180 M CH3NH2 with 0.155 M HBr. Determine each of the following.
a. the pH at one-half of the equivalence point
b. the pH at the equivalence point
c. the pH after adding 6.0 mL of acid beyond the equivalence point
i already found that the initial pH is 11.95, the volume of acid added to reach equivelance point is 29.0mL, and the pH og 6.0mL of added acid is 11.23
