Webcomplex consists of a cobalt(III) ion with two chloride ions and two en molecules acting as ligands, forming an octahedral structure. The chloride ions can occupy either adjacent positions on the octahedron (cis), or the two vertices (trans). The result is geometric isomerism (Fig. 14-3). In the preparation process, we will synthesize the WebIn this experiment, different Cobalt (II) Chloride concentrations are examined using a spectrometer and Labquest instrument. The lab procedure will present that the absorption decreases, the more the solutions of Cobalt (II) Chloride is diluted. The average concentration of the unknown is 0 M .
