Grading:Lab reports are due at the end of each lab period and will be graded based on your experimentalresults, data treatment, and answers to post-lab questions. Part of the grade for each report will include ascore for overall lab performance. This score will be based on your preparedness, attendance, adherenceto safety rules, experimental technique, and work ethic. You will incur point penalties if you arrive late orunprepared, fail to abide by the safety rules or follow directions, and for being uncooperative or disruptiveto the class. For most experiments, you will be required to complete a pre-lab assignment. Pre-labassignments are located at the end of the corresponding section in the lab manual and are due at thebeginning of the lab period. A detailed point breakdown is given below.Colligative Properties: Freezing-Point Depression and Molar Mass. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .20 pointsComputer Analysis of Reaction Kinetics Data. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .20 pointsKinetics of the Reaction of FD&C Red #3 with Bleach. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .20 pointsEnzyme Catalysis with Peroxidase. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .20 pointsChemical Equilibrium: Formation Constant of a Complex Ion System (2 weeks). . . . . . . . . . . . . . . .40 points
