Question:

kerosene and iron(III) iron?

There is a bottle with kerosene, an aqueous solution of iron(III)chloride and sodiume chloride.How to remove the kerosene and iron(III) ions in it?I suggest to use precipitation of Fe so add some hydroxide into it. But how about the kerosene? Some hydroxide can react with kerosene too. The solution will finally change to all soluble except Fe(III)2OH. Then what to do?Or do any body get other good answers except to use hydroxide?

Answer:

Lancenigo di Villorba (TV), Italy Uhmm.a very unusual experiment! Principally, let me get a picture to your Chemical System. In a vessel there are two liquid phases, e.g. Kerosene and an aqueous solution. As you know, they result clearly distinguished since THESE LIQUIDs CANNOT MIX : in the vessel, the lighter liquid (Kerosene) lies upperstanding the heavier one (aqueous solution). But.may I define these liquids? The Kerosene is defined as a hydrocarbon's mixture, e.g. a mixture of hydrocarbons showing CHEMICAL FORMULAE lying between C12-C17. On the other hand, the aqueous solution contains IRON(III) CHLORIDE and SODIUM CHLORIDE characterized by different Chemical Behaviours. ELECTROLYSIS? Can you apply it? Kerosene protects the aqueous phase, so it gets foil to the Electrode Surfaces which become unworthies. Otherwisedid some guy try ELECTROLYTICAL DEPOSITION OF ACTIVE METALs as Sodium and Iron? It results as a very hard experiment! KEROSENE REMOVAL As I wrote, there are two liquid phases which cannot mix. Simply, you will apply the SEPARATOR FUNNEL as a GLASSY LAB-TOOL which you will permit to retrieve the underlying AQUEOUS PHASE ; in a second time, the Kerosene may gets off. IRON(III) SALTs REMOVAL Instead Sodium Salt, IRON(III) CHLORIDE TENDS TO REACT AGAINST WATER ITSELF FeCl3 + H2O --- [FeOH++] + H+ + 3 Cl- [FeOH++] + 2 H2O --- Fe(OH)3 + 2 H+ As you see, the IRON's AQUO-COMPLEX [FeOH++] determines the formation of the red-brownish flakes which is Fe(OH)3. Thus, in order to get easy the overwritten chemical reactions you may ADD CHEMICAL REACTIVEs ABLE TO GIVE A STRONG pH's RISE (e.g. SODA, POTASH or ALKALIEs). This fashion permit you to remove IRON(III) SALTs as its own Hydroxide. I hope this helps you.
do electrolysis of solution 2 get iron
