Sinteza in karakterizacija vzorca nastalega pri reakciji KCr(SO4 )2 x12H2O s kalijevim tiocianatom

Ećimović, Anja (author), Kitanovski, Nives (mentor)

Določila sem sestavo neznanega vzorca, katerega sem sintetizirala z reakcijo med KCr(SO4)2 x12H2O in KSCN. Za določitev sestave sem uporabila fizikalno-kemijske metode, in sicer IR spektroskopijo, UV-Vis spektroskopijo, CHN analizo, rentgensko praškovno analizo ter magnetne meritve. Na podlagi rezultatov izvedenih meritev sem sklepala, da ima neznani vzorec sestavo K3[Cr(NCS)6].

• Title: Characterisation of a sample obtained by reaction between KCr(SO4 )2 x12H2O and KSCN

Abstract

I determined the composition of an unknown sample, which I synthesized using the reaction between KCr(SO4)2 x12H2O and KSCN. To determine the composition, I used physicochemical methods, namely IR spectroscopy, UV-VIS spectroscopy, CHN analysis, X-ray powder analysis, and magnetic measurements. Based on the results of the measurements, I concluded that the unknown sample has the composition K3[Cr(NCS)6].
