Karakterizacija vzorca nastalega pri reakciji bakrovega sulfata in kalijevega oksalata

Marinković, Diana (author), Kitanovski, Nives (mentor)

Neznani vzorec sem identificirala z različnimi metodami s pomočjo osnovnih podatkov o njegovi sintezi (izhodne spojine, topilo). Za identifikacijo neznanega vzorca, sem uporabila infrardečo spektroskopijo, elektronsko spektroskopijo, CHN elementno analizo, rentgensko praškovno analizo, gravimetrično analizo, volumetrično analizo–titracijo in magnetne meritve. Po identifikaciji vzorca–določitvi formule spojine, sem spojino pripravila po že znani sintezni poti in sintetizirani vzorec okarakterizirala z enakim metodami kot neznanega. Dobljene rezultate analiz obeh vzorcev (neznanega in pripravljenega) sem primerjala. Iz primerjave rezultatov sem potrdila, da je neznani vzorec spojina (K4[Cu2(C2O4)4(H2O)2])n.2n(H2O).

Abstract

I identified an unknown sample using various methods and by known basic data about its synthesis (starting compounds, solvent). To identify an unknown sample, I used infrared spectroscopy, electronic spectroscopy, CHN analysis, X-ray powder analysis, gravimetric analysis, titration and magnetic measurements. After identification of the sample – determination of the formula, I prepared compound by the already known synthetic pathway and characterized the prepared sample with the same methods as the unknown. I compared the obtained results of analyzes of both samples (unknown and prepared). The comparison of results confirmed that the unknown sample is (K4[Cu2(C2O4)4(H2O)2])n.2n(H2O).
