Consider the titration of a 28.0 mL sample of 0.175M CH3NH2 witha 0.145M HBr. Determine each of the following.
I already got initial pH: 11.94 and the volume of added acidrequired to reach equivalence point: 33.8 mL.
I still need help with these:
1. The pH of 4.0 mL of added acid.
2. The pH at one-half of the equivalence point.
3. The pH of the equivalence point.
4. The pH after adding 4.0 mL of acid beyond the equivalencepoint.
