Consider the titration of a 50 ml sample of 0.235 m c h nh, with 0.205 m hci. determine each quantity. the k, for methylamine is 5.6 x 10-5. a. calculate the volume of added acid that is required to reach equivalence point. (hint: what equals what at the equivalence point? ) b. the initial ph of c,h-nh, c. calculate the ph after adding 5.0 ml of hci. (hint: what kind of solution have you made? what equation can you use to calculate the ph? ) d. the ph at one-half of the equivalence point. (hint: what equals what at one-half the equivalence point? ) e. the ph at the equivalence point f. the ph after adding 60 ml of hci g. sketch the titration curve. include labels for equivalence point, pk ,buffer region, and where there is excess h+.

1. (8 pts) consider if the initial unknown acid solution used in this experiment started out more dilute. predict any differences you would expect to see in the titration curve ‐ clearly identify what changes, if any, are expected for:  initial ph  ph at the half‐equivalence point  naoh volume needed to reach the equivalence point  ph at the equivalence poin
