Chem 162 Experiment #5
Part A: Preparation of cis-Bis(glycinato)copper(II) monohydrate, Cu(gly)2·H2O g CuSO4·5H2O g g NH2CH2CO2H (glycine) g molar mass CuSO4·5H2O g/mole moles CuSO4·5H2O moles 1 pt molar mass NH2CH2CO2H (glycine) g/mole moles NH2CH2CO2H (glycine) moles 1 pt limiting reagent is 1 pt molar mass Cu(gly)2·H2O g/mole 1 pt (Note for molar mass: each glycine loses the acidic proton in order to be a bidentate ligand) g Cu(gly)2·H2O expected based on limiting reagent g 1 pt g Cu(gly)2·H2O recovered g % Yield % 2 pts Chem 162 Experiment #5: Spectrochemical Series Discuss your % yield. It is high or low? What are the contributing factors to this high or low % yield? (4 pts)
