Laboratory Waste Evaluation
Laboratory waste is considered anything generated during an experiment that is disposed of down the sewer drain, thrown in the garbage, collected in a container for disposal by the UW Environmental Health & Safety department, or released into the environment. Based on the written lab procedure andyour actions during the lab, list the identity and approximate amount (mass or volume) of waste that you generated while performing this experiment. 10 Kimwipes and disposable plastic graduated pipets ~ 0.5 g Copper(II) Sulfate Pentahydrate ~ 0.25 g Glycine ~ 3 mL of 1M HCl
~ 10 g of Sodium Bicarbonate ~15 mL 0.1M Copper (II) Sulfate Solution ~ 5 mL NaCl
~ 1 mL NH4OH ~ 1 mL of 0.20 M en 2 filter paper ~ 1200 mL of Di water ~ 3 mL of Cu(aca)2 complex ~ 3 mL each of the octahedral iron complexes ~ 3 mL each of the Cobalt complexes CHEM 162 Experiment #5: Spectrochemical Series
Goals of this lab:
•Produce a copper coordination compound and evaluate the yield
•Calculate d -orbital splitting energies from spectral data in nanometers •Apply Crystal Field Theory to the comparison of ligand field strengths among groups of coordination complexes
•Assess the accuracy of experimental data and identify sources of error
Your lab report will be graded on the following criteria using a poor/good/excellent rating system :
•Calculations are complete are accurate, with proper use of significant figures and units
•Data collected is reasonable
•Lab report is clear, legible, and neat
•Error analysis is well -supported and valid
