General Chemistry Laboratory II: CHEM 117 Lab Manual builds upon concepts and techniques that were presented in the first semester of the General Chemistry Laboratory course as well as introducing the students to labs that will help them prepare for more advance Chemistry courses. The format of the manual is consistent with that of the first semester where each lab begins with an introduction in which the main concepts of the experiment are described. The introduction is followed by safety instructions and the experimental procedure.
