We will find the mass of the unknown compound that contain cobalt after the experiment. TheCVspectrumof[Co(en)3]Br3hasshownthatareductionpeak Although these two, ligands have the same chemical formula, the former is linear and the latter is branched, giving, rise to complexes with different symmetries. Conclusion What is the purpose of using H2O2 in the synthesis? 2014, 113 (2), 321331. was then added carefully to CuSO 4 .5H 2 O in 50 ml dH 2 O. The mixture was place on a water A infrared spectra of the product was then obtained. ThisAABBsystemisduetotwomagneticallynonequivalent In this experiment, student synthesize two series of cobalt(III) complexes prepared, the tetradentate ligands triethylenetetramine and tris(2-aminoethy0 amine. and Its formula is written [Co (NH 3)4Co3]NO3. Whereas triethylenetetramine coordinates to form a, , symmetry axis, tris (2-aminoethy) amine forms a complex that has a, The purpose of the lab is to synthesize a cobalt (III) that is prepared by using cobalt (II), the, amine, and reagent which convert cobalt(II) to cobalt(III). ion. The experiment was carried out according to the detail directions written on the paper. ,formaldehydeandammonia.
