Chemistry 12:  Please bring some food items for the two families that we are taking care of.  Today we learned about buffers (Section 4.19) and I assigned # 131 - 134, which is due Monday.  Lab 20G was handed in today.  Make sure that U4 # 108 - 118 from Thursday is finished too.  Acid Base unit test on Tuesday.
