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].
