Chemistry 12:  We started off with a short review of Sections 4.1 to 4.3, and I checked that U4# 1-19 are done.  We took notes on Strong vs Weak acids, after which we read 4.6 and did Unit 6 # 21-24, 26,27.  These problems are due Tuesday.  Lab 20G was prepared, and we finished Part I and some of Part II.  We will continue with Lab 20G on Tuesday.

Chemistry 11: Today we did lab 20C Part I (Questions 1-3) and we worked on the legal green Stoichiometry WS.  Both are due on Tuesday.  Our Reactions Unit Test will happen on Friday next week.  Nice work on your very first titration!  We will do Lab 20C Part II on Tuesday.
