Experiment 6Ligand Replacement Reaction Synthesis of [Ni(NH3)6]Cl2Objective1.Sysnthesis of hexaamminenickel (II) chlorideReagentsNickel (II) chlorideConcentrated AmmoniaEthanolIceApparatusGraduated cylinderFilter paperBuchner funnelPetri dishIntroductionMany transition metal form octahedral complexe with H2O when in aqueous solution.Examples include pink [Co(H2O)6]2+, green [Ni(H2O)6]2+and pale-blue [Cu(H2O)6]2+. Additionof ammonia to such solutions results in a series subtitution reactions in which the watermolecules are replaced by ammonia molecules. For example, when concentrated aqueousammonia is added to the colour changes to the violet color of the ion.
