Consider the titration of a 28.0−mLsample of 0.180 M CH3NH2 with 0.155 M HBr. Determine each of thefollowing.
the inital pH
the volume of added acid required to reach the equivalencepoint
the pH at 6.0 mL of added acid
the pH at one-half the equivalence point
the pH at the eqivalence point
the pH after adding 6.0 mL of acid beyond the equivalencepoint
