CHEM 162 Experiment 5: Spectrochemical Series Complete Solution 2023
CHEM 162 Experiment 5: Spectrochemical Series Complete Solution 2023. 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 Part A: Preparation of cis-Bis(glycinato)copper(II) monohydrate, Cu(gly)2 ·H2O mass CuSO4 ·5H2O g mass NH2CH2CO2H (glycine) g molar mass CuSO4 ·5H2O g/mole moles CuSO4 ·5H2O moles molar mass NH2CH2CO2H (glycine) g/mole moles NH2CH2CO2H (glycine) moles limiting reagent is molar mass Cu(gly)2 ·H2O g/mole (Note for molar mass: each glycine loses the acidic proton in order to be a bidentate ligand) mass Cu(gly)2 ·H2O expected based on limiting reagent g mass Cu(gly)2 ·H2O recovered g % Yield % 0.5070 0.2450 249.68 0. 75.070 0.
