Pre-lab 5.2 Electronic Spectra of Metal Complexes—Polyelectronic Systems 

Procedure 5.2.1 Visible Spectroscopic Analysis of Tris(bidentate chelate)cobalt(lll) Complexes 

Quantitatively prepare three solutions of 5 x 10-3 M (record exact concentration) cobalt(ni) complex solution (dH20) using an analytical balance and volumetric flasks. 

Calculate the molar absorptivity for each absorption at its maximum wavelength for your complex using Beer s law (see Results Summary sheet).
