Synthesis procedure I -1. 0 Introduction A Cobalt-Amine-Hide compound is synthesized from cobalt (II) chloride hexameter. An orange-tinted solid is produced and is considered to be unknown since the specific aligned amounts are unknown. By determining the percent composition of various elements and compounds in the unknown, its true identity can be predicted. Chloride, ammonia, and cobalt are three examples of percent compositions determined to help narrow the selection of possible unknowns.
Iterations using Nauseas and HCI to determine percent cobalt and ammonia, respectively, are used.Silver nitrate is used to precipitate he chloride ions in the unknown, which can be measured to determine the percent composition of chloride in the unknown. The results from these three major analyses helped to draw the conclusion that the unknown is in fact -2. 0 Synthesis/Analysis of Cobalt-Amine-Halide Compound (Procedure 1, pigs 16-7)) A cobalt (Ill) amine halide compound was prepared by making a solution of cobalt (II) chloride hexameter and ammonium chloride (Enoch) to liberate the Co (II) in the solution. ‘Activated” charcoal and ammonia are then added to the solution.
