[Wasted4440]

      I had previously posted a topic on my attempt to synthesize magnetic ionic liquids of the class [EMIM][M(EDTA)] (M=Fe³⁺, Co³⁺, Cr³⁺) here: http://www.chemicalforums.com/index.php?topic=74420.0

      However, after several more failed attempts to synthesize these liquids according to the reference paper listed, I attempted a side experiment of creating the complex [EMIM]FeCl₄ found using this paper, which details the synthesis of [BMIM]FeCl₄: https://www.jstage.jst.go.jp/article/cl/33/12/33_12_1590/_pdf

      My question is: I started by adding [EMIM]Br to an aqueous solution of FeCl₃, presumably resulting in the formation of [EMIM]FeCl₃Br. On a whim, I added an excess of NaCl to the solution to push the reaction from [EMIM]FeCl₃Br to [EMIM]FeCl₄ via what I presume is a ligand substitution mechanism. Is my reasoning here correct?
