This is an IN-LAB Report due before the end of the lab period. Record all of your data and observations
in your lab notebook, then NEATLY transfer your results to the report sheet.
Grading: 60 points total (Lab notebook pages are 10 points; Report is 50 points)
By signing below, you certify that you have not falsified data, that you have not plagiarized any part of this lab report, an d
that all calculations and responses other than the reporting of raw data are your own independent work. Failure to sign this
declaration will result in 5 points being deducted from your report score.
Signature:
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
Note: the molecular formula
for the complex will give you
moles NH2CH2CO2H (glycine) moles 1 pt information about the
reaction stoichiometry for
determining the limiting
limiting reagent is 1 pt reagent.
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
Discuss your % yield. It is high or low? What are the contributing factors to this high or low % yield? (4 pts)
