Cobalt-Halide Synthesis

In this experiment, preparation of the cobalt-amine-halide compound was performed by synthesis procedure II in the lab manual. This required the students to obtain cobalt (II) chloride hexahydrate and distilled (DI) water, as well as preparing slurry of NH4Cl, where NH3 will be derived from, and concentrated ammonia. Both of those mixture where later put together and hydrogen peroxide was added. The solution was heated and 4M HCl was added. The mixture was eventually cooled and suction filtered to collect the crystals (see pg. 18 for details). The end result, of this experiment was 6.5913 grams of beautiful red-violet color
