consider the titration of a 26.0 mL sample of .175M CH3NH2 with .155M HBr. Determine each of the following.
1) the initial pH
2) the volume of added acid required to reach the equivalence point
3) the pH at 6mL of added acid
4) the pH at one-half of the equivalence point
5) the pH at the equivalence point
6) the pH after adding 6.0 mL of acid beyond the equivalence point
