The ball-and-stick model of iron(III) acetate actually does not have acetate ligands on the iron. It actually shows an unknown, or at least unusual ligand, technically a dianion (doubly-negatively charged ion) theoretically arising from double deprotonation of acetaldehyde hydrate. As such, it could be called the acetaldehyde dianion, or in a more IUPAC style, the ethane-1,1-bis(olate)dianion. In condensed structural formulas, what you have on display in the ball-and-stick model is CH3-CH(O-)2 attached to the (brown) Fe(III) ion, when it should be CH3-C(=O)-O-, a.k.a., CH3COO- or CH3CO2-, all of which are for acetate. To correct it, you should generate the structure without a CH bond on the carbon that has the two oxyanions. That carbon is being shown as an sp3 hybrid (geometry shown is tetrahedral about the carbon), and it should be an sp2 hybrid (geometry should be trigonal planar). Moreover, the ideal geometry would also include equivalent C-O bond lengths, reflecting the delocalization of the negative charge of the acetate ion over all three atoms in the carboxylate group. I was going to point one of my chemistry classes to this picture, but I saw the error and thought I would delay until the picture is fixed, if that is still possible. —Preceding unsigned comment added by Whiteashprof (talk • contribs) 21:50, 1 November 2010 (UTC)
Query: Iron(III) acetate is described in the box on the right of the pages as being insoluble in water, but the illustration on the left claims to show `an aqueous solution' of it? Should this be an aqueous suspension or a solution in ethanol? Clarification please. Barney Bruchstein (talk) —Preceding undated comment added 15:56, 13 September 2011 (UTC).
Soluble in water or not?
[edit]Picture labelled "Aqueous solution of..." and chembox claims "insoluble in water". Make up yer mind.

Is this compound soluble in water or not?
[edit]Chembox says it's insoluble. But clearly, vinegar can dissolve iron (III) oxide rust. There are conflicting sources, some saying it's soluble but others say it's not. Furthermore, the structure shown on the page is a coordination complex, but PubChem and ChemSpider both show it as a normal salt. Could this have anything to do with its solubility? Does it have 2 forms, one a soluble salt and another an insoluble complex? I am not an expert, but there is another comment saying the complex is straight up wrong.

- "But clearly, vinegar can dissolve iron (III) oxide rust."
- Can it? I tried it myself and the results were disappointing. I don't think it's "soluble", the brownish-red powder creates tiny particles that form a colloid. This is not "solubility". By "dissolve", it is implied at breaking the ionic compound apart, which does not seem to happen. 2804:187C:83BF:EE00:BCBC:9558:4C2:7471 (talk) 21:02, 21 October 2024 (UTC)
