Karakterizacija (NH4)2[MoX5H2O] (X = Br, Cl)

Ozimek, Sara (author), Kitanovski, Nives (mentor)

Z analizo rezultatov izbranih metod sem potrdila sestavo dveh vzorcev podobne kemijske sestave, v katerih sta zastopana kloridni oz. bromidni ligand. Opravila sem razklop vzorcev. Na ostankih, nastalih po razklopu, sem določila vsebnost halogenida na osnovi gravimetrične analize in potenciometrične titracije. Za karakterizacijo vzorcev spojin (NH4)2[MoX5H2O] (X = Cl (1), Br (2)) sem uporabila še rezultate elementne CHN analize, vibracijske in elektronske spektroskopije, rentgenske praškovne analize in magnetnih meritev.

Abstract

By analysing the results of the selected methods, I confirmed the composition of two samples of similar chemical composition, in which chloride or bromide ligand were present. I did the deconstruction of the samples and then determined the halide content in the residues formed after the decomposition, based on gravimetric analysis and potentiometric titration. To characterize the samples of compounds (NH4)2[MoX5H2O] (X = Cl (1), Br (2)), I also used the results of elemental CHN analysis, vibrational and electronic spectroscopy, X-ray powder analysis and magnetic measurements.
