We use Ferric Chloride (FeCl3) in the lab to test for the presence (or in some case absence) of phenols, although some enols will also yield positive results. The OH (hydroxy group) which is attached directly to an aromatic nucleus (Benzene, for example) is detected by the Ferric chloride. It is important to note that alcohols do not undergo the reaction. Phenols will typically yield dramatic purple,blue,red or green color as an indication of a positive test. FeCl3 will also indicate the presence of aliphatic acids (that is, non-aromatic organic acids, such as Acetic acid) turning the solution a yellow color. Aromatic acids will test as a beige-tan color. Enols will also show a characteristic yellow color. It is also important to understand that not all phenols will test positively in the presence of the FeCl3 reagent. A good example of this is in highly hindered phenols which do not yield positive tests. However, a negative test is not completely conclusive, so other tests can be preformed to verify the absence of a phenol (such as NMR and IR spectroscopy) We use Ferric Chloride (FeCl3) in the lab to test for the presence (or in some case absence) of phenols, although some enols will also yield positive results.

considering it only contains iron (Fe) and chlorine (Cl), none.
The ferric chloride solution is acidic.
Ionic bond exists between the atoms of ferric chloride. This is because ferric chloride is formed when iron, a metal, reacts with chlorine, a non-metal, to form a compound where electrons are transferred from iron to chlorine, resulting in the formation of positively charged iron ions and negatively charged chloride ions.
The chemical name for FeCl2 is Iron(II) chloride or ferrous chloride. Ferrous chloride is a solid with a high melting point.
FeCl3
When ferric chloride (FeCl3) is mixed with iron (Fe), the iron displaces the chloride ion to form ferrous chloride (FeCl2) and iron chloride (FeCl3). The chemical equation is: FeCl3 + Fe -> FeCl2 + FeCl3.
Aniline on heating with Ferric chloride forms Ferric anilide and HCl. 3C6H5-NH2 + FeCl3 = (C6H5-NH)3Fe + 3HCl
The reaction between potassium thiocyanate and ferric chloride forms a blood-red complex called ferric thiocyanate. This complex is formed due to the reaction between the thiocyanate ions from potassium thiocyanate and the iron(III) ions from ferric chloride. The balanced chemical equation for the reaction is: FeCl3 + 3 KSCN -> Fe(SCN)3 + 3 KCl.
FeCl3
Ferric or Iron (III) = Fe3+Chloride = Cl-Fe3+ + Cl- = Fe2Cl
The reaction between benzoic acid (C6H5COOH) and ferric chloride (FeCl3) forms a complex between the iron ion and the oxygen atom of the carboxyl group. The general equation for this reaction is C6H5COOH + FeCl3 → [Fe(C6H5COO)3] + 3HCl.
The balanced equation for ferric chloride (FeCl3) reacting with sodium hydroxide (NaOH) is: FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl
Both compound have covalent bonds with formula FeCl3 and AlCl3.
When aqueous Ferric chloride is allow to react with Sodium hydroxide the reddish brown ppts. of ferric hydroxide are formed. FeCl3 (aq.) + 3NaOH = Fe(OH)3 + 3NaClThey form precipitates of Ferric hydroxide.
Ferric chloride contains the elements iron and chlorine.
considering it only contains iron (Fe) and chlorine (Cl), none.
No, they have different formulas and have iron in different oxidation states. Ferrous chloride or Iron II chloride has the Fe2+ ion and the formula FeCl2 Ferric chloride or Iron III chloride has the Fe3+ ion and the formula FeCl3
