Chemistry 11:  Today we did Lab 16A, about polar and non-polar solvents and solutes.  The Solutions Practice Test is due today, but I will provide an answer key on Monday.  Our Solutions test is on Tuesday.

Chemistry 12:  After a short discussion of the key points of Electrochemistry so far (loss of electrons is oxidation, gain of electrons is reduction, oxidation number is the charge an atom would have if it were an ion) we did lab 21D.  Nothing from your lab is due Monday. Unit 5 # 1-6 should be done by Monday's class.
