In synthesis of an iron salt experiment a solid chemical compound will be made and then purified by crystallization, decantation, recrystallization, and vacuum filtration. The salt is composed of three ions and water so the salt is a hydrate. One of the component ions, oxalate, is made of covalently bonded carbon and oxygen. This ion acts as a unit during the reaction to form the iron salt compound. Indicate either True or False for each statement on the iron salt synthesis below: Recrystallization is used to purify the iron salt. The iron salt is a hydrate. Chloride is one of the ions that compose the iron salt made in the experiment. The analysis for the percent Fe and K ions will be done in the Acid-Base Experiment. The synthesis and analysis of the iron salt is done as a group but calculations and report writing are done individually. The iron salt is composed of three ions and water. A. True B. False

BACKGROUND: Synthesis of Potassium Iron
(III) Oxalate Hydrate Salt
The iron(II) ions from
Fe(NH4)2(SO4)2•6H2O
will be precipitated as iron(II) oxalate.
Fe^2+(aq) + C2O4^2-(aq) --> FeC2O4 (s)
The supernatant liquid, containing the ammonium and sulfate
ions, as well as excess oxalate ions and oxalic acid will be
decanted and discarded. The solid will then be re-dissolved and the
iron(II) ions will be oxidized to iron(III) ions by reaction with
hydrogen peroxide.
2Fe^2+(aq) + H2O2(aq) --> 2Fe^3+(aq) +2 OH^ - (aq)

2. It is the oxalate ion (C2O4 2- ), which is the conjugate base of oxalic acid, that will serve as the chelating agent for Fe3+ in our experiment. The goal is to determine the empirical formula of the coordination compound that will form. Let’s imagine some of the possibilities. a. A complex ion is comprised of a metal atom or ion at its center, to which is bonded molecules or ions (called ligands). What are the common coordination numbers...

Synthesis and Analysis of a Copper Oxalate Complex (Formal Report) This is a 3-week experiment and it will be the basis for your formal report, details to follow. Coordination complexes are molecules or ions formed when a central metal ions form bonds to nonmetal ligands. These interactions are Lewis acid/base interactions where the metal ion acts as a Lewis acid and the ligand acts as a Lewis base. For example, a common coordination compound is the copper ammine complex [Cu(NH3),],...

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
