I calculated the equivalence point to be 33.3 mL with the pH being 5.47 at this point. The initial pH was 10.80. I have the points for region1, region2, and region3 (assuming these are correct). The problem I am having is calculating region4 after the equivalence point... I use 34 mL and end up getting a pH of 0.54... I don't know if this is right or what I am doing wrong. Any RAPID help is GREATLY appreciated!I have to have this done by Wednesday at 5 p.m!</blockquote>
