Today we started with a mini-review of various Solubility Topics, followed by a short discussion about Hard water and soft water.  Read 3.9, then do the following problems from Hebdon: Unit 3 # 47, 51-53, 64-66.  The second half was spent on Lab 19B - all Questions, Follow-up Questions, and a Conclusion. Lab 19B is due Friday.

We started off with a mini-review, then did Lab 19C, which is due Friday.  I checked Unit 3 # 40-50 and 29-33.  We finished off with a short discussion of KTrial, which is just like "Q" that we learned about in the Equilibrium Unit.  Due next class is Unit 3 # 56-63.

Today the Solubility Lab was collected. We used the ideas of Solubility and Solubility Product to solve problems # 40 - 50 in Unit 3.  After, we learned about precipitation reactions, and did the Precipitation Reaction mini-Lab where we practiced writing the 3 equations associated with these reactions (Formula Equation, Complete Ionic Equation, Net Ionic Equation).  We also learned about separating mixtures, and in particular separating mixtures of ions.   Due next class is the Precipitation Reactions WS, Unit 3 # 29-33 and #40-50
