AP Day 132

Today we discussed how to interpret titration curves...telling what was being titrated (SA/WA/SB/WB), what combination of S/W analyte & titrant were being used (based on pH at the equivalence point), buffers and how to calculate the pH of a buffer solution (see the online practice at http://www.sciencegeek.net/Activities/Buffers-Composition.html )  We also described the half-equivalence method for determining the pKa of a weak acid.

Unit 12 Test is tomorrow.  Check the blog for assignment to be completed for Thursday.
